Hello, We are a small body shop/car lot based in South Kentucky. Over the last few months (4-6) we have had 4 Acadia's (also had 2 Blazer's) with the heated seats not working. We have changed the switches on both sides, the heated seat module, and had that at the dealer for relearning, still can't get them fixed. our local dealer is now telling us we need to change BCM and have that relearned as well. Has anyone else had these issues? How did you fix it?
