Air Conditioning Problem
Installed A&A kit couple of weeks ago. and the A/C worked fine this morning then tonight I push the A/c control and it flashed and would not come on just hot air blew. The belt is installed and was never removed. Coolant is charged, the climate control also says that it is -15ext. when it is freaking 95 degrees outside. Im confused and any help would be great thanks.

Any Codes??
If they don't tell you anything, I would check your external temperature sensor circuit.
If the HVAC control module is at -15ext then the AC will not come on.
I believe the sensor is the one down in front of the radiator on the passenger side. Trace the wiring back to the HVAC Module.
You can test the sensor with a resistor, say a 5K. The ext temp should read about 100F with the resistor in place.
