I can not make my AC work. Checked the fuses, relay is good. Jumped the relay connection and the compressor runs and cools great. (Contemplating a toggle switch)

I am pretty sure I have a bad temp sensor in the Auto Climate Control or maybe the Climate Control Panel is screwed up. I am thinking maybe the temperature sensor is not the culprit as the AC won't cycle on defrost either.

Have to be a genius to "test" the CCP, but wouldn't mind taking a chance replacing it if someone knowledgeable told me that CCP failure is a common problem. Was hoping for thoughts and what you'd try next. Also, if you knew of a wiring diagram link, that'd be swell.

first of all thank u so much for ur donation it really helps to keep this site going and answering everyones questions.the control units dont go bad that often.i would make sure ur a/c is properly charged with 2.09lbs of charge.i posted the wire diagram for u.i would start by checking the outside air temp sensor located in the grill make sure its plugged in and the wires and terminal tightness is good on the connector.also i would have the a/c control unit scanned for codes u might have to go to the dealer for that one unless u find a shop that has a advanced scanner with the software which would probably be hard to find.but with codes it would give u a starting point and i could get u the trouble tree to follow for the code.let me know what u find.
