I recently had my coolant system replaced, and now have problems with the air conditioning, which is not in the same area I am told. When I turn on the air conditioning it blow hot air on the driver side and cold on the passenger side, it has dual contols. I seem to even have heat when using just the vent, or when everything is turned off. Could it be a damper stuck? And if so where is it located?

I have a 2001 Regal that has the same problem (from time to time). I have noticed that this only occurs in very humid conditions. If I shut the car off, and restart, the problem usually goes away. For me, this happens so rarely, that I have not taken the car in to the shop. I suspect some sensor has some humidity and after the car warms up (even just for a short time), a restart makes the problem disappear.
