I have a 1999 Chevy suburban 4x4 1500 5.7. My problem is my a/c, i took it to a guy to check it for free and after that its been blowing hot. did some research to see how to fill it back up and this is what i did, i first vacuumed out the system then replaced the orifice filter and seals in the compressor. i then put it all back together again and vacuum once more. the gauges were reading fine. so i started my car put a/c on high and placed the oil 150 on the low side with high side off. when i was recharging the high side was valve was turned off. after putting in the oil my gauges were at 0. so i went ahead with the 134a 12oz can open up valve to release air then opened up low side and only after that one can my gauges were reading 47psi on low side and about 242psi on high. what the hell went wrong no leaks and no air in the system, so what now?
