A/C cutting in/out

kingcudi · July 18th, 2011, 03:46 PM

guys my a/c has been cutting in and out a lot recently..still blows cold but when I get into the gas a little bit more than chill it blows warmer, and randomly/often when i'm cruising at a constant speed. my friend said it could be the vent check valve but i am unsure, Mattman said it could be the a/c clutch but its fine at idle, and can't check it when I'm driving..
help?

I would think that it's either a AC clutch or compressor problem.

I'm really not sure how to test that while you're driving though. Can you get it to do that while revved and not moving?

a/c delete kit, simple fix.

I looked at the clutch while revving it on the throttle body and it didnt stop spinning, so how am I to check the compressor for problems?

Well your AC should cycle.. so you should see the clutch catch and release.

you could be low on freon....

Is it supposed to turn on and off a few times a minute? From what i noticed it didn't release while the air was on until I jumped the low pressure switch on the canister so I could keep the compressor running while I checked the freon pressure..its sitting at 37psi. The first time I jumped it it released but I tried it again and the clutch stayed engaged..idk what else to look for
