My A/C is not blowing cold air on my 2000 cadillac deville. I pulled all the codes and got nothing referring to refrigerant low or compressor off. On my 1996 deville I had the same problem but the only difference is my message center displayed the problem and the error showed in my codes. Should these codes be showing on my 2000 cadillac deville? Or is there something else that could be wrong? Also I recently just replaced my mode actuator door. I doubt their could be any connection to the cold air problem but I could be wrong.
