I have a 99 3.8 and the AC kinda stopped working. it worked fine, then wouldn't turn on until the car was hot, now won't turn on at all. Clutch is not spinning. all fuses fine. I tried to put in R134 and the pressure was very high..
So should I release the pressure and start over with fresh R134.
For one, only evacuate the refridgerant if you know how to CORRECTLY. It is extremely damaging to the environment and in just about every state, against the law otherwise. Have you tried checking your pressure switch for it to be faulty?
