Re: ac problem

Are you able to check high and low pressure together?
You may have air in the system and it may be over pressured at idle.
Just guessing but sounds logical.

Re: ac problem

was over charged. brought it down where it should be. was cold as hell til i drove it and sat in it and then it started the whole thing of warm cold warm again.

dad suggests pump it out and recharged it. i don't think it will help but what else should i check or do?

Re: ac problem

why do you not think it will help?
At least it will confirm that you have no air in there and you can take it from there.
I'd get some leak detector in there too if I was you. That way you can monitor connections easier seeing as there will be luminous green around a bad one with leak detector.
what sort of frequency is your compressor clutching....constant or short bursts?
