Have you checked your fuses

I had this problem, but only on the driver's side (with leather seats). Sometimes the switch would come on, but I could not get it to go back off (and the seat would not heat).
I ended up removing the drivers front seat cover (only the bottom part), folding it back from the driver's door to the middle of the car. You also have to unplug the wiring harness underneath the seat. I found a black spot burned in the foam. This is where a wire had broken. I carefully pulled the wire together, then soldered it. I put everything back together, and it has been working ever since (about 6 months - and getting lots of use in the middle of the winter).
I think the only way to replace the heated seat wires is to replace the whole seat cover. I was glad I could fix mine by soldering it.

i checked the fuses and they are both good
My 2003 Buick Lesabre heated seat quit working. Then the passenger heated seat quit working. Now the fan is only blowing cold air. I replaced the fuses. How can I check a relay?
