I have a 99 Eldorado and the A/C light came on. The compressor won't run now, guessing that is tripped off as a protection measure since the freon is too low. I'm using a freon can (134a), but the system won't accept it. Yes, I am hooking it up to the low side. I think I need to get that compressor to trip back on for the system to accept the freon. I was wondering if there is a procedure to bypass the compressor automatic shut down? I want to run the compressor to get the freon into the system. It's possible that I'm completely off base on all of this btw, if so please tell me. If not then please tell me the procedure to turn the compressor back on. Thanks in advance!
