Default A/C not working - blowing warm air

My A/C is not working at all. And icing on the cake : I'm vacationing in the California desert....

My car has 99000 miles on it.
Looking for suggestions :
- any recommendations on what to check for?
- should I take it to the closest pepboys/autozone? anything specific I should ask them to check for?

Thanks!

First thing I'd check is whether the compressor is engaging when you turn the A/C on. All you have to do is look under the hood.

Autozone would be in a EPA me$$ if they have unlicensed yahoos put a gauge on customers cars. Pep boys should have at least one licensed guy who can do something.

Hopefully your low on refrigerant because of your cars age. They need to vac the system and recharge and test for leaks.

Took it to Pepboys and this was exactly the problem. Low on refrigerant and leaks on both O-rings.

Replaced the 134 and leaking rings and my AC seems to be doing well!

FYI : Cost me $175 at Pepboys btw.

^wow...a bottle of 134a is like $9.xx, pressure gauge can't be more than $15, and a set of o-rings for a/c system is $10...whre did $175 come from?

but congrats on fixing your a/c 2 weeks ago my car had no a/c either, but the heat motivated me to recharge the system ftw.

check out your condensor for any visable damage/holes from rocks or whatever.

hopefully not the case!

*edit* sorry didn't see that you already fixed the problem. Hooray!

Does anyone know where to get an AC compressor clutch without having to buy the whole compressor?

Labour for 1 hour's work?
I didn't argue ... mechanic seemed competent. I was in a hurry... with my wife complaining about the heat. I would have gladly parted with double the amount I think

I just built my motor and need to recharge my A/C.. I purchased the refrigerant from Autozone but I'm unsure of which port do I fill with? Is it the line that is near the radiator that connects directly to the A/C compressor or is it the line near the fire wall?

I searched and cannot find a simple write up on how to recharge the A/C system!

Thanks in advance,

Sean

The reason you can't find a simple write-up is that proper AC service isn't a DIY. Yes you can go to the parts store, buy some cans of 134 and stick them in, but that is not the right way to do it- especially if the system has been completely discharged and left empty/open for some time.
The right way to do it is take it to a shop that has the needed equipment and certifications, they will pump the system down into a vacuum to remove any air and moisture, then refill it to the proper charge level using manifold gauges. Depending on how long the system has been empty it may be recommended to replace the drier unit as it's likely contaminated.
Yes this will cost more than doing it yourself but in the long run you'll be better off. The system will work at full efficiency and won't be subject to expensive failure (i.e. compressor) later on.

Its been empty for 2 weeks.. All I did was let all the A/C out from the bleeder at the compressor. I did not see any oil come out while releasing the valve. But I will definitely take your advise and get it done professionally at a certified shop!

Thanks for your response!

I love the monday morning repair quarterbacks that tell everyone what their repairs should cost. In case you forgot parts are priced differently in geographical areas and so is the labor. You know they will not put it on for free so that is also where the extra money comes in.

Mulder is correct.
There is no sure write up for a/c being there are many components that can cause the a/c not to work(Thermister, condensor,compressor, o-rings, hoses, etc). Some just charge it up with freon and be done with it which is a bad idea. If there is a leak somewhere, it allows air and moisture in the system which doesn't play well with other components like the receiver dryer/accumulator.

OK thanks.
In the past when I fully build my cars I usually take out the A/C and power steering so I never came across this situation before..

Thanks guys and I will let you all know how it turns out!
