why does the heat / ac system have a mind of its own?
there are times I think my car is possessed
I usually have the AUTO system off, mostly so I can have the recirc set to on.
I'll look over and find it turned off..
or other times I look over and see that the air conditioning is turned on..
or I've turned on the read defroster and find it has turned itself off before the rear window is defrosted..
