I have 2002 Buick LeSabre. The air conditioner compressor is running, the refrigerant line is cold after the expansion valve. The fan blows, but hot air comes out of the vents. It does not have dual zone. And I have not tried the heater switch yet.

Use manifold gauge set and get the readings. Don't forget there are ambient temp sensors inside and out on climate control! The inside one could be plgged with dirt, or defective.
