A/C going off and on

[twalker31794]

Alright guys my a/c is going crazy it will run sometimes then sometimes nothing. It's on in the car but doesn't blow any air. When it does work it blows cold. Not sure what's going on. Any help is appreciated

Check whether it needs gas. You can get refill cans at a local parts store with a gage. There is a low pressure switch in the freon circuit that will disconnect teh compressor if the pressure is too low. This is the likely problem if it blows cold for a while and then kicks off.

I have a similar problem, except it works fine if it's not too hot. When it gets over about 85 degrees, it will run cold for 40 seconds or so, then shut off for a few minutes. The dealer is replacing a blower motor and relay.
