1995 Pontiac Bonneville SSE-I have a problem with the heat and air control. I think I have it narrowed down to the AC/heater Contraol Swith and have the part but I can't locate where it goes...Is it behind the control panel and if so where? The part almost looks like a relay. FYI-I checked the fuses, relays and had the AC checked in the summer when I first had this proble. (the Temp control indicator for the Inside temp flashes when i first start the car. Oh I sarted having problems with the heat now that it's cold. I checked the hoses and I don't think I have a thermosat problem. And occassionally the heat and a/c work. So i figured it must be electrical and checked fuses and relays but now i beleieve itis the AC/Heater Control Switch. Any help?
