2002 cavalier AC only works while driving, At idle it runs for a little while then blows hot and heats up past 195+. It sounds like the compressor. Any ideas?

 

i'm having the same problem. i have no idea what it is, i've never had a vehicle with working air conditioning :-\

 

Yeah, it sucks... it sounds like the ac compressor to me. But, I could be wrong. Or, it could also be that theres a leak somewhere? Though someone might know?

 

Check that your engine cooling fan is coming on when the A/C is turned on. If the fan motor is bad then the A/C compressor will cycle on & off. If the fan is not coming on with the A/C on OR when the engine heats up past 210 then check the fan fuse and relay. On the Cav. '04 they're both in a black fuse block under the hood. If fan proves to be good then you should check the freon pressure on the low side. It may be just low enough to make the compressor get too hot. I had to replace the cooling fan recently on said Cav. and there's a trick to getting the fan shroud off so let us know what you found.

 

Ok, ill do that! Thanks for the write up! Ill be working on the car this weekend...

 

I had a similar problem...
I fixed it with the simple splice of a new pigtail that I ordered from ROCKAUTO.com
