ac compressor

[powerstroke23]

my ac compressor wont stay engaged it will engage for a second or two then let go any ideas, maybe the shim?

Low on freon?

freon, low pressure switch, or shim in the ac clutch.

For mine it was the shim. Bypassing the low pressure switch would make it turn on for a few seconds and then it would stop again. Sometimes romping on it to 3000+rpms would get it to kick in for a few seconds, then it would blow warm again.

mine blows cold when the rpms are over a grand but when Im idling at operating temp it goes warm.

Mine was doing this and when I hooked up the pressure gauge from autozone I could watch the pressure go up, it would turn on, the pressure would drop and in a few seconds the compressor would turn off. over and over again. Added 2 cans of the freon from autozone and now it works well.

Mine was doing the exact same thing... I added one large can of freon, works great now.

Could be other things, but you are most likely just low on freon, get a can or two and a gauge.

that was when i noticed it, while i was chargeing it up
