ok i been having a lot of ac issues i found out my relay was grounding to close the relay. i checked out my gorunds and everything seems good i replaced my climate control module thinking the gorund might be bad in there and still the same issue. so now i gorunded it to my car from the relay and ac works but i still get the "service ac compressor off" and " low refrigerant" and its full. so could it be my pcm or does anyone have any advice the car is 97 eldorado
