Correct

That was the pressure when it was running, clutch was engaged. Regarding the 2lbs, that’s what I was charged for. It was a shop that did the work evacuating the system and refilling it, I’d have to think they looked the specs up and just rounded it up when they charged me. Even if it were overfilled, wouldn’t the high side pressure be higher when it’s running and the clutch is engaged?

So I picked up a set of AC gauges. Both high and low side are about 108. If it were overfilled the high side would still be reading much higher, right? Everything I read is pointing to a bad compressor, but it’s got a brand new AC Delco compressor. Clutch operates as it should, on when the AC button is on, off when it’s not. Checked with a UV light, no leaks anywhere that I can see. im pulling my damn hair out and I’m bald, so it’s tough ?

So my 14 Silverado has about 60k miles, belt broke between the crank and AC compressor. Found out the compressor was completely locked up. Replaced the compressor and expansion valve, new o-rings as well. Brought it to get evacuated and recharged, and was told there’s no leaks. They put just under 2lbs in, but I still have warm air. I only have a gauge that came on a Freon can, and the low side is way high, around 140. Compressor and clutch are both working fine. Any ideas what the problem could be?
