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?
I will leave them unplugged, till I figure this out

The only thing I can think of is that the switches might be bad.

yeah, that's what I figured, I'm just going to leave them unplugged, are the switches still available??

 

[KD7ONE]

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.

thanks,I'll look into that, for now I'll just leave them unhooked.

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

I could get the wire colors going in to the connectors in the morning if it would help
