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!
