Seat Heaters .... Mind of Their Own

[pdxrealtor]

Lol... I don't know. I've never read about it but that doesn't mean much.

Reminds me of a Volkswagen

Pain (heat) in the ass

I heard that there is a module (BCM) that controls those things and that if it starts faulting it will do things like that (along with rolling down windows when ever it wants to)

Given, I might be wrong. (guruerror? any insight?)

BTW, the BCM is under you drivers seat
any moisture will mess it up

I'll jump in... Every time I start mine up the drivers side is on high and my ass gets fried.... I'd like to know more also!!

Thank god mine don't do this...heat seaters always make me feel like I need to take a dump.

I had teh same problem with my 05. But just on the drivers side.
The bun warmers would turn on full tilt, I'd turn them off, and then a short while later, back on again. Eventually, they'd stay off.

I did find (IIRC) that there is a module under the driver's side seat that controls the seat heaters. I priced it out, and it was about $400 bux.
I took a chance and ordered a new switch for the door panel from hummers online. Think it was about $130 bux. This solved my problem!!
Luckily I never had problems with the passenger side door panel switch.

$130 beat $400, so maybe try changing that door panel switch!
Good luck!
