Just got my car back from the dealer today, for the seat heater issue. Your post explains a lot, I took my car in last week, on Tues. Jan. 3 to replace both the driver's and passenger's seat heaters, none of them worked - Since I bought the car (used) the driver's side hasn't worked and the passenger side quit working a while back. I didn't get it back until last Fri. I get home and check the passenger seat and it doesn't work at all, also all I felt on the driver's side was the bottom warming up. So I took it back in on Monday and asked them to recheck it, they explained that they replaced all the heating elements in the seats initially, so maybe it was the control module you were talking about - Needless to say it took them 8 days to fix the seat heaters, but now at least it's over - hopefully I won't have to make another trip to the dealer anytime soon.
