More A/C Issues
I just recently had my 1995 Blazers A/C system recharged, and a high pressure valve replaced because it was leaking freon. The A/C system was doing just fine for a while, then all of the sudden it would start to work intermittently. It would run for about 5 - 10 minutes then not run at all. Now it isn't running at all. A friend of mine said it might have something to do with a pressure switch. However, there are quite a few pressure switches/valves w/ an A/C system, so it is hard to tell which one it could be. I was wondering if anyone has had this problem. If it is a switch, what switch could it possibly be, how easy is it to replace, and can it be replaced w/o evacuating the system again. Any help on this issue would be greatly appreciated. Thank you very much.

RE: More A/C Issues
The AC cycling switch is the most common thing but that would keep it from workinfg at all... not intermitten so I dont think that is the problem
i think its low on freeon there is a leak somewhere the condensors are common to leak... usually by the lower pass side corner i would suggest getting a shot of tracer dye and looking for am leak with a uv light.

Thanks Dory. However, when the A/C was last recharged, a dye was put through the system. I will have to check to see if there are any leaks. The freon levels are where they should be according to the gauge I have. Thanks again for getting a professional's take on the issue.

as well as that, if the truck is overheating or the fan clutch is bad, the ac will not work as well

Well I would still look for a leak... but if a presure switch needs to be replaced, it should be able to be done without evac and recharge. I know that on the newer ones, the ac cycling switck does not require that and usually its the switch right next to the reciever/dryer (the thing that looks like a metal can under the hood)
