I have a 1992 Grand Prix 3.1 with a heater/AC problem. Fans work great, the hot/cold lever seems to change the blowing air from cool to warm, and the air output is split between the defrost and floorboard. It doesn't matter which switch I depress (AC, defrost, vent, floor, etc), the air flow doesn't change. Seemingly half through the floorboard and half through the defrost ducts. Even the fans speeds work fine. A couple of knowledgeable guys have told me they think the problem is in the 'blend back door actuator' but I haven't been able to find any instructions anywhere on how best to change this component and I had to wonder too, if there isn't some way to just run the AC compressor directly to the battery through a fused switch versus tearing into my dash when I'm not entirely sure what I'm looking for. Anyone have any experience changing one of these components?
have the same problem?
