I believe this was helpful, my a/c wouldn’t turn on out of nowhere, but as I’m driving cold air is coming out just barely. Cold air would come out through vents only as I drive though, but just barely. I just had the compressor and condenser replaced two months ago as well

Same issue. Turns cold on crank and on the highway. I swapped my motor & tuned for E fans, fans ran on toggle switch. For some reason my computer is sending an intermittent ground to the AC relay. That ground should be constant to keep the compressor on

thankyou gave me more to go on.. I bought the truck and the compressor was bypassed didn't have a belt on it I can turn the clutch by hand and it is doesn't have very much freon it very very very little almost none. I checked the power to my low pressure switch a at actuator and I'm not getting power there would that happen because there's no freon in it so the little button on my control module is not sending power? I'm going to bypass that low pressure plug and give direct power to the low pressure switch if I can or can I jump it from the relay so I can get some freon in it you think that's a good idea or? and mine's a 2003 GMC 1500 pickup. I know 9 times out of 10 when someone takes the belt off it needs a compressor they just don't want to do it but some people don't realize I might just need a clutch for the compressor so I figured I'd give it a shot

Then most likely the compressor took a crap internally or its low on ref due to a leak Leak causes can be dirty condenser coil being so dirty it raised pressures making the ref busting out thru cracks or killing the seals..so most likely change out all seals possible and condenser if its extreme clogged up in the fins

2001 Silverado 2500hd Gas - If i jump the low side pressure switch at the accumulator the compressor doesnt cycle, i was checking the fuse under the dash and i noticed when i test the fuse there the compressor kicks on everything blows cold and the ac light on the dash module under the radio will turn on again. All other fuses work, i swapped relays, still cant get it to cycle by pressing the ac button. Possibly a bad ground? I have no way to check pressures at the moment.

Yeah I have an 05 silverado with similar issues. I know my pressures are good but the only way I can get the compressor to run is to jump it at the relay. I have 4.8 volts at the low pressure switch but jumping it doesn't engage the compressor. When I jump it at the relay, it works perfectly and it even started working for a few days perfectly but it quit again.

Hoping my wife’s is something easy like this. I’ve been tapping the compressor for 2 summers intermittently when it won’t come on with the switch in the cab. About 3 months ago the tensioner would rattle on a hard takeoff and hit the transmission lines, new tensioner and belt-same issue. It fixed itself as quick as the issue came along. Now a week ago I was sitting with the kids while she ran in the store and it seized up and the belt went to squealing. Must have smoked the compressor because it will turn on, may squeal, may not, but it won’t cool for nothing. Mechanic wouldn’t touch it because he said voltage at the connector on the compressor was wonky. He said electrical issue and this is about the best thing I could think of.
