OPINION
Justice YÁÑEZ
delivered the Opinion of the Court,
in which Justices DORSEY and HINOJOSA joined.
In this original mandamus proceeding, relators James and Clara Van Blarcum (“the Van Blarcums”) request this Court to direct the respondent, Judge Marisela Sal-daña, to vacate her order of February 2, 1999 compelling binding arbitration of disputes arising from relators’ purchase of a mobile home. We conditionally grant the writ.
In the underlying proceeding, the Van Blarcums filed suit against the mobile home manufacturer, American Homestar of Lancaster, Inc. (“Homestar”); the retailer, Nationwide Housing Systems, Inc. (“Nationwide”); and the finance company, Associates Housing Finance Services, Inc. d/b/a Ford Housing Finance Services (“Associates”),1 alleging, inter alia, violations of the Texas Deceptive Trade Practices— Consumer Protection Act (“DTPA”),2 the Texas Manufactured Housing Standards Act,3 and breach of express and implied warranties. Anticipating that defendants would move to compel arbitration, they also requested a stay of arbitration, alleging the arbitration agreement they executed in connection with purchasing the home is void and unenforceable because it violates the Magnuson-Moss Warranty Act (“the Act”).4
This proceeding presents questions of first impression in Texas: (1) whether under the Act, a warrantor is prohibited from requiring the use of binding arbitration to resolve claims arising under written warranties for consumer goods pursuant to an arbitration agreement signed at the time of purchase, and (2) whether the trial court’s decision in relying on the Federal Arbitration Act (FAA) and its general mandate favoring arbitration to give effect to the arbitration agreement compelling binding arbitration of claims arising under a written warranty was an abuse of discretion.
By two issues, the Van Blarcums contend the trial court’s decision compelling arbitration was an abuse of discretion because: (1) the Act precludes binding arbitration of consumer warranty disputes and (2) by requiring the Van Blarcums to bear the costs of arbitration, the arbitration agreement effectively deprives them of a forum for resolving disputes and is therefore unconscionable.
[488]*488Facts
On May 23, 1997, the Van Blarcums and Nationwide executed a Retail Installment Contract-Security Agreement (“the Contract”) for the purchase of a mobile home in Corpus Christi, Texas. At the same time, and as part of the Contract, they executed with Nationwide a separate Arbitration Agreement (“the Agreement”). The Agreement specified that “all claims, disputes, and controversies arising out of or relating in any way to the sale, purchase, or occupancy of the [mobile home] including ... any claims under any warranties ... [would] be resolved by means of final and binding arbitration.” The Agreement also provided it “inures to the benefit of ... the manufacturer of the Home ... as fully as if the manufacturer was a signatory to the Retail Installment Contract” and “to the benefit of ... any lender or mortgagee ... who provides financing for the purchase of the Home.” At the time of purchase, the Van Blarcums were provided with a retailer’s written warranty by Nationwide. The mobile home was also covered by a separate written warranty by Homestar, which was not provided.
Subsequent to the purchase and installation of the mobile home, the Van Blarcums notified Nationwide and Homestar of various defects in its construction and installation. Despite receiving assurances that the deficiencies would be remedied, numerous complaints remained unsatisfied nine months after the Van Blarcums first requested that warranty repairs be made. On or about July 31, 1998, the Van Blar-cums filed an action in County Court-at-Law Number Three, Nueces County, Texas, seeking, inter alia, declaratory and injunctive relief, damages, and a stay of arbitration. Nationwide and Homestar filed a motion to compel binding arbitration of the Van Blarcums’ claims, arguing that the Agreement must be given effect under both the Federal Arbitration Act (FAA)5 and the Texas Arbitration Act (TAA),6 and that their dispute with the Van Blarcums was encompassed within the terms of the Agreement. Following a hearing on February 2, 1999, Judge Salda-ña ordered the parties to proceed to arbitration in accordance with the terms of the Agreement, and stayed litigation of the suit pending resolution of the matter by the arbitrator. Thereafter, the Van Blar-cums filed a Motion for Reconsideration, which the trial court denied following a second hearing on April 15,1999.
The Real Parties’ Jurisdictional Challenges
Before addressing the Van Blar-cums’ issues, we must first consider the real parties’ jurisdictional challenges. Real parties assert this Court lacks jurisdiction over the trial court’s order compelling arbitration pursuant to the TAA because mandamus is not an appropriate remedy under the TAA. Real parties contend the motion to compel was urged pursuant to both the FAA and the TAA, and because it was granted in its entirety, mandamus is improper as to “that aspect” of the order under the TAA.
In support of their argument that mandamus relief is unavailable under the TAA, real parties cite Jack B. Anglin Co. Inc. v. Tipps, 842 S.W.2d 266, 272 (Tex. 1992). Real parties’ reliance on Anglin is misplaced. In Anglin, the supreme court, in reviewing a trial court’s order denying a motion to compel arbitration, held mandamus relief is available when a trial court improperly denies a party’s motion to compel arbitration brought under the FAA. Id. at 272-73. In dicta, the court stated that “[b]oth the Texas and Federal Acts permit a party to appeal from an interlocutory order granting or denying a request to compel arbitration.” Id. at 271-72.7 At [489]*489issue in the present case is an order by the trial court granting real parties’ motion to compel arbitration. We therefore reject real parties’ argument that Anglin is applicable to the facts before us.
We need not, however, determine, whether mandamus relief is available under the Texas Act because the Agreement specifically provides arbitration “shall be governed by the provisions of the Federal Arbitration Act and the rules of the AAA [American Arbitration Association].” The parties may designate which arbitration act they wish to control proceedings under the contract, and the courts will honor that choice. See D. Wilson Constr. Co. v. Cris Equipment Co., 988 S.W.2d 388, 392 n. 3 (Tex.App.—Corpus Christi 1999, orig. proceeding [leave requested] ). Moreover, the FAA applies to all claims arising from a transaction involving interstate commerce, 9 U.S.C.A. § 2 (2000), and it is undisputed that the sale of the mobile home “involves” commerce. We conclude the transaction “involves” commerce. See Allied-Bruce Terminix Cos. v. Dobson, 513 U.S. 265, 272-75, 276-78, 115 S.Ct. 834, 130 L.Ed.2d 753 (1995); L & L Kempwood Assocs., L.P. v. Omega Builders, Inc., 9 S.W.3d 125, 127 (Tex.1999). Accordingly, for purposes of determining jurisdiction, we view the order compelling arbitration as issuing pursuant to the FAA.
The FAA declares written provisions for arbitration “valid, irrevocable, and enforceable, save upon such grounds as exist at law or in equity for the revocation of any contract.” 9 U.S.C.A. § 2 (2000). The Van Blarcums claim the Agreement is invalid and unenforceable because it requires binding arbitration of written warranty claims in violation of the Magnuson-Moss Act.
Mandamus is the proper remedy for an order compelling arbitration under the FAA. Freds v. Canales, 877 S.W.2d 283, 284 (Tex.1994); Turford v. Underwood, 952 S.W.2d 641, 643 (Tex.App.—Beaumont 1997) (orig.proceeding). Mandamus will issue only to correct a clear abuse of discretion or the violation of a duty imposed by law when there is no other adequate remedy by law. Walker v. Packer, 827 S.W.2d 833, 839-40 (Tex.1992) (orig.proceeding). A clear abuse of discretion occurs when the court’s decision on a factual issue is so arbitrary and capricious to amount to clear error or is a violation of legal duty. A clear abuse of discretion also exists with any error in analyzing or applying the law. Id. A party who is compelled to arbitrate without having [490]*490agreed to do so will have lost its right to have the dispute resolved by litigation and has no adequate remedy by appeal. Freís, 877 S.W.2d at 284. Absent a valid agreement between the parties to arbitrate the claims at issue, there is no obligation to arbitrate. Id. If arbitration is ordered without such an agreement, the trial court has abused its discretion in ordering the arbitration. Id.
Magnuson-Moss Act Overrides Federal Arbitration Act
In their first issue, the Van Blar-cums contend the trial court abused its discretion in compelling arbitration because under the Act, a consumer cannot be compelled to submit a claim to binding arbitration when the consumer purchases a product covered by written manufacturer and retailer warranties. Real parties contend, however, that because nothing in the Act’s text, legislative history, or purpose precludes arbitration, the FAA, rather than the Act, is controlling.
Congress passed the FAA in 1925. The FAA ‘s “primary purpose” is to ensure “that private agreements to arbitrate are enforced according to their terms.” Volt Info. Sciences, Inc. v. Board of Trustees, 489 U.S. 468, 479, 109 S.Ct. 1248, 103 L.Ed.2d 488 (1989); Solis v. Evins, 951 S.W.2d 44, 48 (Tex.App.—Corpus Christi 1997, writ denied). The U.S. Supreme Court has stated, however, that “[l]ike any statutory directive, the [FAA’s] mandate may be overridden by a contrary congressional command.” Shearson/American Express, Inc. v. McMahon, 482 U.S. 220, 226, 107 S.Ct. 2332, 96 L.Ed.2d 185 (1987). The burden is on the party opposing arbitration to show that Congress intended to preclude a waiver of judicial remedies for the statutory rights at issue. Id. at 227, 107 S.Ct. 2332. Such Congressional intent can be gleaned from the statute’s text or legislative history, or from an inherent conflict between the FAA’s endorsement of arbitration and the statute’s underlying purposes. Id. The McMahon test for determining whether to enforce arbitration agreements involving statutory claims has been stated as follows:
... for a statutory claim to not be arbi-trable, the party opposing arbitration must demonstrate that Congress intended to prohibit or limit waiver of the judicial forum. If the party is unable to do so, then it must demonstrate that an “inherent conflict” exists between the FAA and the statute’s underlying purposes.
Knepp v. Credit Acceptance Corp. (In re Knepp), 229 B.R. 821, 833 (Bankr.N.D.Ala. 1999).
In 1974, Congress passed the Magnu-son-Moss Act “to improve the adequacy of information available to consumers, [and] prevent deception.” 15 U.S.C.A. § 2302(a) (2000). The Act sets out specific requirements regarding disclosures, duties and remedies associated with warranties on consumer products.8 Under the Act, any consumer who is damaged by a warrantor’s failure to comply with an obligation under a written or implied warranty or service contract may “bring suit for damages and other legal and equitable relief.” 15 U.S.C.A. § 2310(d)(1) (2000).
Where an irreconcilable inconsistency is encountered between statutory provisions, the more recently enacted and more specific statute covering a specific subject controls over the earlier and more general one, unless there is evidence of a clear legislative intent to the contrary. See HCSC-Laundry v. United States, 450 U.S. 1, 6, 101 S.Ct. 836, 67 L.Ed.2d 1 (1981); Balfour Beatty Bahamas, Ltd. v. Bush, 170 F.3d 1048, 1050 (11th Cir.1999); ICC v. Southern Ry. Co., 543 F.2d 534, 539 (5th Cir.1976). When Congress enacts new legislation, it is presumed to be in light of the earlier enactments. See Unit[491]*491ed States v. Trident Seafoods Corp., 92 F.3d 855, 862 (9th Cir.1996), cert. denied, 519 U.S. 1109, 117 S.Ct. 944, 136 L.Ed.2d 833 (1997).
The Van Blarcums contend the Act’s statutory scheme, legislative history, and underlying purpose indicate that Congress intended to preserve a consumer’s access to a judicial forum. After examining the Act’s statutory provisions, legislative history, the comments and rules promulgated by the Federal Trade Commission (FTC), and case law interpreting the Act, we agree. In Southern Energy Homes, Inc. v. Lee, 732 So.2d 994, 999 (Ala.1999), the Alabama Supreme Court addressed this issue and concluded that “the general provisions of [the FAA] are superseded by the subsequent and specific provisions in the Magnuson-Moss Act by which Congress has prohibited the inclusion in written warranties of clauses calling for binding arbitration.” Id. at 999-1000.
Real parties contend the Van Blarcums have failed to meet their burden under the McMahon test to establish by the Act’s text, legislative history, or purpose that Congress intended to preclude enforcement of the FAA. Real parties cite Gilmer v. Interstate/Johnson Lane Corp., 500 U.S. 20, 111 S.Ct. 1647, 114 L.Ed.2d 26 (1991), and McMahon, 482 U.S. at 220, 107 S.Ct. 2332, for the proposition that certain statutory claims (such as claims arising under the Securities Exchange Act,9 the Racketeer Influenced and Corrupt Organizations Act (RICO),10 and the Age Discrimination in Employment Act (ADEA)11) are arbi-trable, notwithstanding the fact that the applicable statute in each case provides for a judicial forum. See Gilmer, 500 U.S. at 35, 111 S.Ct. 1647; McMahon, 482 U.S. at 230, 238, 242,107 S.Ct. 2332.
As the Southern Energy court notes, the question in each of those cases was “whether a statutory right of action provided by Congress superseded the FAA so as to prohibit the enforcement of arbitration agreements.” Southern Energy, 732 So.2d at 998. The Southern Energy court distinguished Gilmer and McMahon, as well as several other cases, noting that the decisions in each case were based on findings that there was nothing in the text of the statute at issue or its legislative history explicitly precluding binding arbitration. Id. at 998-99. The court noted the “silence in the text” and “silence in the legislative history.” Id. at 998. The Southern Energy court concluded that “[t]he Mag-nuson-Moss Act is different, both in text and in legislative history,” in that it clearly reflects an intent by Congress to prohibit the use of binding arbitration. Id. at 999. We agree. Accordingly, we hold that the FAA is superseded by the Act’s specific provisions prohibiting the use of binding arbitration clauses in written warranties.
Definition of “Consumer Product”
Real parties also challenge the applicability of the Act by alleging that the mobile home at issue does not fall within the scope of the Act’s “consumer product” definition. The Act defines “consumer product” as “any tangible personal property which is distributed in commerce and which is normally used for personal, family, or household purposes (including any such property intended to be attached to or installed in any real property without regard to whether it is so attached or installed).” 15 U.S.C.A. § 2301(1) (2000). It is undisputed that the Van Blarcums’ mobile home was “distributed in commerce.”
Real parties rely on a statement by Congressman Moss during floor debate on the Act that “[a] house would not fall within the definition of consumer product since a house is not quite ‘tangible personal property,’ “12 to support their contention that [492]*492the Van Blarcums’ mobile home does not fit within the intended definition of “consumer product.” Additionally, they claim support in Clark v. Jim Walter Homes, 719 F.Supp. 1037 (M.D.Ala.1989). Their reliance on Clark, however, is misplaced. In Clark, plaintiffs contracted with a builder for the construction of a prefabricated or modular home. Id. at 1044. The court distinguished between a good that is movable and one that is stationary, holding a prefabricated home is stationary once construction is completed. Id. at 1043-44.
Unlike a prefabricated home that is stationary once attached to land, a mobile home by its very nature is a movable dwelling. FTC rules interpreting the Act state that any ambiguity about whether a product is covered under a definition should be “resolved in favor of coverage.” 16 C.F.R. § 700.1(a) (2000). Thus, keeping in mind the broad scope of the Act, we conclude although a stationary dwelling falls outside the reach of “consumer good” because it is “real property,” a mobile home is within the definition because it remains “tangible personal property” even though it may be attached to real property. See 16 C.F.R. § 700.1(a)-(f) (2000).
Arbitration Agreement as Separate Document
Real parties next argue the Act does not bar binding arbitration in this case because the Agreement executed by the Van Blarcums was a “separate contract” and was not included in the “written warranty.” In support, they argue that the Van Blarcums’ reliance on section 2310(a)(3) of the Act as a bar to binding arbitration is misplaced because that section applies only to warrantors who choose to include in their written warranties a requirement that a consumer resort to an informal dispute settlement mechanism (IDSM) prior to pursuing a legal remedy for breach of warranty.13 Because here, according to real parties, no arbitration provision or any type of IDSM was incorporated into the terms of the written warranties, the rationale that binding arbitration is precluded (because the provisions only allow warrantors to require consumers to “initially resort” to such informal procedures before filing suit)14' is inapplicable. Therefore, real parties contend that nothing in the Act prohibits the use of binding arbitration provisions in a separate agreement.
As noted, the Agreement states it “is executed contemporaneously with, and is part of,” the Contract. It further states it “inures to the benefit of’ Homestar “as fully as if the manufacturer was a signatory” to the Contract, and “inures to the benefit of’ any lender providing financing for the purchase of the home. We conclude the Agreement is “incorporated” into and “is part of’ the Contract. The written warranties by Nationwide and Homestar are contained in separate documents and make no reference to the Agreement. Nonetheless, we conclude that if the Act prohibits a warrantor from including an absolute bar on judicial remedies in its warranty, it also precludes a warrantor from incorporating such an absolute bar in a corresponding sales contract. Allowing warrantors to do in a separate agreement what they are clearly prohibited from doing in a written warranty would be to allow an “end-run” around the Act and would completely eviscerate its prohibition against binding arbitration. See Wilson v. Waverlee Homes, 954 F.Supp. 1530, 1539 (M.DAla.1997), aff'd, 127 F.3d 40 (11th Cir.1997) (a warrantor may not “do by surrogate or vicarious means what it is forbidden to do on its own behalf.”)
Relators’ Challenge to Binding Arbitration
Section 2312(c) of the Act authorizes the FTC to promulgate rules govern[493]*493ing implementation of the Act. 15 U.S.C. 2312(c)(2000). Accordingly, the FTC has published guides and rules interpreting the Act, including the following: (1) Rule 701, specifying the information that must appear in a written warranty on a consumer product; (2) Rule 702, detailing the obligations of sellers and warrantors to make warranty information available to consumers prior to purchase; and (3) Rule 703, specifying the minimum procedural standards for any internal dispute settlement mechanism (“IDSM”), which must be followed by any warrantor who wishes to incorporate an IDSM, through a prior resort requirement, into the terms of a written consumer product warranty.15 Recently, the FTC published its “Final Action,”16 64 Fed.Reg. 19700 (1999), a review of warranty-related rules and guides, including its Interpretations of the Act (“Interpretations”) 17 and Rules 701, 702, and 703.
The Act generally applies to written warranties covering consumer products. See 16 C.F.R. § 700.3(c). Section 2301(5) of the Act defines a “warrantor” as “any supplier or other person who gives or offers to give a written warranty or who is or may be obligated under an implied warranty.” 15 U.S.C. § 2301(5); see also 16 C.F.R. § 701.1(g) (defining “warrantor” as “any supplier or other person who gives or offers to give a written warranty.”). Here, both Homestar and Nationwide provided separate written warranties and are therefore written “warrantors” under the Act.
Section 700.8 of the FTC’s Interpretations prohibits a warrantor from indicating in any warranty or service contract that the decision of the warrantor, service contractor, or any designated third party is final or binding in any dispute involving the warranty or service contract. 16 C.F.R. § 700.8 (emphasis added). It further characterizes any such statements as “deceptive” because the Act “gives state and federal courts jurisdiction over suits for breach of warranty and service contract.” Id. (emphasis added).
The Act encourages (but does not require) warrantors to establish informal dispute settlement mechanisms for the fair and expeditious settlement of consumer disputes, and authorizes the FTC to establish minimum procedures for such informal mechanisms. 15 U.S.C. § 2310(a)(1), (2). The rules provide the minimum standards which must be met by any informal mechanism that a warrantor incorporates into a written warranty. 16 C.F.R § 703. Although a warrantor may, if it elects to do so, include a provision requiring a consumer to pursue informal dispute resolution procedures before filing suit,18 the rules [494]*494require that any such mechanism inform consumers that if they are dissatisfied with the outcome of the procedures, they may pursue legal remedies, id. at § 708.5(g)(1), and that “[djecisions of the [mjechanism shall not be binding on any person.” Id. at § 703.5(j)- Moreover, the rules prohibit a warrantor from charging consumers a fee for use of the mechanism. Id. at § 703.3(a).
Section 2310(d) provides that “a consumer who is damaged by the failure of a supplier, warrantor, or service contractor-to comply with any obligation under this chapter, or under a written warranty, implied warranty, or service contract, may bring suit for damages” or other relief in state or federal court. 15 U.S.C. § 2310(d)(1).
Rule 703 has been interpreted to prohibit the use of binding arbitration clauses in written warranties.19 The Commission recently reaffirmed its view that “reference within the written warranty to any binding non-judicial remedy is prohibited by the Rule and the Act.” 64 Fed.Reg. at 19708 (quoting 40 Fed.Reg. 60168, 60211 (1975)). The Commission, noting “that this interpretation continues to be correct,” declined to amend the rule, and stated, “Rule 703 will continue to prohibit warrantors from including binding arbitration clauses in their contracts with consumers that would require consumers to submit warranty disputes to binding arbitration.” Id. at 19708-09. The Commission cited with approval a decision by an Alabama federal district court, Wilson v.. Waverlee Homes, Inc., 954 F.Supp. at 1530, holding that the Act prohibits warrantors from including binding arbitration clauses in written warranties on consumer products. 64 Fed. Reg. at 19709. In Waverlee, the issue before the court was whether a defendant manufacturer could rely on an arbitration clause in an installment contract between a mobile home retailer and a consumer (where the manufacturer was not a party to the sales contract) to compel the consumer to submit to binding arbitration. The court held the manufacturer could not compel arbitration in such circumstances. Because the Act precluded the manufacturer from including a binding arbitration agreement in its own written warranty to the consumer, the court concluded the manufacturer could not “do by surrogate or vicarious means what it is forbidden to do on its own behalf.” Waverlee, 954 F.Supp. at 1539. The court reasoned that a contrary holding would result in “the complete and utter evisceration of the Magnuson-Moss Act.” Id. at .1540.
In Southern Energy, the Alabama Supreme Court reached a similar conclusion:
Suffice it to say that although several sections of the Magnuson-Moss Act make reference to informal dispute-resolution procedures or mechanisms, those and other provisions also make it clear that a consumer is to have access to a judicial remedy. In short, a warranty may expressly set forth an informal dispute-resolution mechanism and may make the use of that mechanism' a prerequisite for filing a court action, but it may not provide that the use of such a mechanism is binding or that it is a bar to a court action.
Southern Energy, 732 So.2d at 996 (citations omitted) (emphasis supplied).
[495]*495The dissent agrees that the Act bars binding arbitration of the Van Blarcums’ written warranty claims, but concludes that arbitration of their implied warranty and non-warranty claims may be compelled because the Act does not preclude it. In support, the dissent cites Boyd v. Homes of Legend, Inc., 981 F.Supp. 1428 (M.D.Ala.1997), remanded on jurisdictional grounds by 188 F.3d 1294, 1300 (11th Cir. 1999) (instructions given to district court to vacate in part), and Rhode v. E & T Investments, Inc., 6 F.Supp.2d 1322 (M.D.Ala.1998). Both are distinguishable.
In Boyd, the issue was whether a defendant mobile home dealer who was a signatory to a purchase contract containing an arbitration agreement but had not provided any written warranty to the consumer could compel arbitration of the consumer’s claims involving only non-written warranties. The court noted that this question was not presented in Waverlee, where the defendant manufacturer had provided a written warranty to the consumer. Boyd, 981 F.Supp. at 1435. In distinguishing Waverlee, the court noted:
Here, however, the [dealer] defendants are not written warrantors under the Magnuson-Moss Act, having provided no written warranty to the [purchaser] plaintiffs. Consequently, they are not subject to the numerous provisions of the Act aimed exclusively at written warranties, including those governing the establishment of informal dispute procedures, which were shown in Wav-erlee Homes to be the source of the clearest expressions of congressional intent to preclude binding arbitration in certain circumstances.
The [dealer] defendants are, however, ‘warrantors’ under the Act, which defines such a person as ‘any supplier or other person ... who is or may be obligated under an implied warranty, 15 U.S .C.A. § 2301(5), and defines an implied warranty as one ‘arising under State law (as modified by ... this title) in connection with the sale by a supplier of a consumer product.’ 15 U.S.C.A. § 2301(7). Thus, the [dealer] defendants are subject to those provisions of the Act that address warranties in general, and implied warranties in particular, but not those specifically directed to written warranties.
Id. at 1436-37 (emphasis supplied) (footnotes omitted). The Boyd court concluded that because the dealer was not a “written warrantor, ” the Act did not preclude binding arbitration of the consumers’ implied and other non-warranty claims. Id. (emphasis supplied). Significantly, the Boyd court noted that it was not addressing the “interesting question” now before this Court:
It is interesting to note that the court is not now confronted with a claim where a consumer seeks to pursue both written and non-written warranty claims against a warrantor. Therefore, the court need not address the interesting question of whether the Magnuson-Moss Act would restrict binding arbitration of the non-written warranty claim as well, in particular if it were closely related to, or intertwined with, the written warranty claim. Although this issue could have been raised in Waverlee Homes, it was not.
Id. at 1435 n. 8.
In Rhode, the plaintiff brought breach of warranty claims against both the manufacturer and the seller of a mobile home. Rhode, 6 F.Supp.2d at 1325. As in Waver-lee, the manufacturer had provided the plaintiff with a written warranty, but was a signatory to neither the installment contract, which included an arbitration agreement, nor a separate arbitration agreement between the plaintiff and the seller. Id. at 1328-29. The plaintiffs breach of warranty claims against the manufacturer were not intertwined with his breach of warranty claims against the seller. Id. at 1331. As in Waverlee, the court held the arbitration agreement included in the sales contract was not applicable to the manufacturer, and refused to compel arbitration [496]*496of plaintiffs claims against the manufacturer. Id.
The mobile home seller in Rhode, like the seller in Boyd, was a signatory to both an installment contract containing an arbitration agreement and a separate arbitration agreement, but did not provide the plaintiff with a written warranty. Id. at 1332. In fact, the installment contract between the plaintiff and seller specifically disclaimed all warranties except the implied warranties that could not be avoided by law. Id. Nonetheless, the court held that insofar as the plaintiffs claims against the seller included express-warranty claims, the Act precluded the seller from invoking the arbitration clause as to those claims, but that the seller could compel arbitration of plaintiffs breach of implied-warranty claims. Id.
Thus, although both the Boyd and Rhode courts distinguished between breach of written-warranty and implied-warranty claims, the distinction in each case was based on the fact that the seller had not provided a written ivarranty to the plaintiff. In the present case, however, both Homestar (the manufacturer) and Nationwide (the seller) provided separate written warranties. Accordingly, both are written warrantors under the Act and are precluded from including in a written warranty any provision calling for binding arbitration.
“It is a familiar law of contracts that an illegal agreement is unenforceable.” Palma v. Verex Assur., Inc., 79 F.3d 1453, 1462 (5th Cir.1996) (quoting DiFrancesco v. Houston Gen. Ins. Co., 858 S.W.2d 595, 598 (Tex.App.—Texarkana 1993, no writ)); Phillips v. Phillips, 820 S.W.2d 785, 789 (Tex.1991). The arbitration Agreement between Nationwide and the Van Blar-cums 20 provides for binding arbitration of all “claims under any warranties, either express or implied ” in violation of the Act (emphasis supplied). Because the Agreement compels arbitration of the Van Blar-cums’ written warranty claims in violation of the Act, we hold the Agreement is invalid and unenforceable in its entirety, both as to the Van Blarcums’ written warranty and implied warranty claims. We sustain the Van Blarcums’ first issue.
Our holding that no valid arbitration agreement exists makes it is unnecessary for us to address the Van Blarcums’ second issue. See Tex.R.App.P. 47.1.
We conditionally GRANT the Van Blar-cums’ petition for mandamus and direct the respondent to vacate her order of February 2, 1999 compelling arbitration. The writ will issue only if respondent fails to act promptly in accord with this opinion.
