Just curious if anyone had done any research regarding this?
Judging from the electrical diagram its getting a simple 12v from the switch and grounds itself. The only part that has any complications is the thermostat (that presumedly switches the seat from high to low once a certain temp is attained). I dont know if it gets a higher voltage from the switch for "high" or if the t-stat figures all that out.
Dorman makes a replacement kit thats affordable that comes with all necessary wiring.
Currently my system works but only on the seat back. At least thats how it feels, I havent gotten a DVOM to see whats actually getting warm. Both seats are doing the same thing really.
Any advice/comments would be appreciated!
