Talk about insanity lol reading the same problem but from 20 different perspectives. I feel like this has seriously become the hardest problem of the car to diagnose the exact cause and fix for. It's also lovely that 100F is right around the corner. It'll be 93F in Oklahoma tomorrow it might as well be 110 with the humidity.


Two things, are you positive the system has a charge? It has a low pressure switch that could be holding the compressor clutch off. On another note, see ( https://www.crossfireforum.org/forum...ion-check.html ), if the low pressure switch isn't holding it off maybe something here can help (yeah, I know, more 'reading'?).

Good luck, stay focused, one thing at a time will keep you on track! BTW, the low pressure switch, IF it is reading as an 'open' across the two terminals, it is not going to allow the clutch solenoid to engage. While you have that low pressure switch unplugged, check the actual solenoid on the compressor for continuity (remember do not have the car running when your testing the switch or the clutch).
