as I started My burb today, I heard the motors for the rear heat/ac come on by themselves. I immediately unplugged them both,this has only happened yesterday and today. the rocker switches for them are in the proper off position. before I unplugged them,they seemed to cycle on and off.why would they suddenly come on like that? :confused:
I will leave them unplugged, till I figure this out

I'm sure they are. Try contacting your local Chevy dealership. They can probably get them for you......if that's what the problem is.

Could be a bad relay switch (anyone have a schematic?) that decided to turn itself on/off.
