Bwmjj Posted January 4, 2015 Share Posted January 4, 2015 The lights come on for the heated seats but no heat. Is there a relay that controls the heat to the seats? Both seats have no heat in them which makes me suspect there is a relay controlling both. Any advice would be helpful. Thanks Quote Link to comment Share on other sites More sharing options...
eugene.s Posted January 11, 2015 Share Posted January 11, 2015 Hi, I would check the fuses first (ref you car's manual). Relays and diagrams are available from the Repair Manual (RM) for your car (model/year). RM costs a fortune but in rare cases some people told me they were able to find publicly available RMs for their cars in the internet.

pj8708 Posted July 16, 2016 Share Posted July 16, 2016 Hi Eugene, Another source for tech info is Toyota Information services. Use of any and all things Lexus, Toyota, and Scion can be found there. The fee is only $15.00 for two days. Paul Quote Link to comment Share on other sites More sharing options...
