There are several AC System PCM monitored items.. Depends on what goes bad. If it is something MECHANICAL, then the answer is most likely NO, unless it results in one of the below listed DTCs:
DTC P0530 A/C Refrigerant Pressure Sensor Circuit Malfunction
DTC P0531 A/C Refrigerant Pressure Sensor Circuit Range/Performance
DTC P0532 Air Conditioning (A/C) Refrigerant Pressure Sensor Circuit Low Voltage

Ok Ill start it up and see if I can get a code to come up. Havent had one pop up but was just wondering since the Compressor isn't kicking in when I hit the button. The light isn't blinking and stays on. But no cold air since the comp isn't kicking on. System is also charged per one of those cheap little gauges you get with a bottle of Freon. But its showing OVER charged. It worked before I pulled the motor out and put it back in. Thanks guys.

Is the electrical connection on the Compressor clutch properly connected?
YES
Pull the DTCs and see what HVAC ones pop up.

Ahhh ok makes sense now why it looked over charged. Redid the connection twice just to make sure I had a good connection. Ran the codes and didn't get any except for the Air pump which I disconnected and am going to remove and turn off once I get tuned. Guess Ill play with it somemore and look around. Hopefully its something stupid. Im just running through my head at work thinking about it.
