Hey man I am having the same problem. I took out the drivers side seat and went through all the wiring and all was good. I then took out the passengers side, which works, heat module under the seat and put it in the drivers side and still didn't work. I have read on other sites that it may be a wire in the seat foam that has burned out. I didn't want to take it that far yet of taking the leather off, I am in Vegas and really don't need it but it just bugs me when things don't work. I will see if I can find more details about how they fixed the problems and let you know. Let me know if you figure it out, would love to fix mine too. Good luck
