This is a stupid question and I hope I dont insult you, but when you drive do you rest your arm and hand on your arm rest on the door? GM had a bulletin for heated seats coming on from customers bumping the button when they hit a bump with there arm resting on the arm rest. They came out with a replacement so the button sits farther in the door panel. Just an Idea for ya to consider. If you dont think that is the problem have the system check with a code scanner. Other wise I have seen those buttons stick internally causing the heated seats to come on when you hit a bump.

Rhall77, no such thing as a stupid question, thanks for your thought but I don't have that kind of luck.
