you may need to put another can of freon/refrigerant in it.

Any car's AC system works on the principle that an expanding gas results in a lower temperature. The way the system works utilizes this by compressing AC fluid (freon or 410A) with a compressor that is run off the drive belts. Then it's run though an expansion chamber (sometimes called valve), cooling the incoming air passing through.

If your coolant is still good, and it should be, have a mechanic run a pressure test on the AC setup. As long as there are no leaks, this should tell you if you need a new compressors.

Compressors are nasty parts, they involve very fine machinery running at high speeds (many thousands of RPMs) under high pressures. Needless to say, they break often.

A new compressor shouldn't be more the four hundred dollars.

we have a 02 suburban and it does the same thing...if you roll the windows down and just let the car run for like 5 to 10 min. and it might work after that...cause thats what i do but dont like blast the a/c as soon as you get in it cause it messes it up..and be sure to turn the a/c off before you turn suburban off

i think the freon should do the trick, well at least i would have hoped...but now i hear about the compressor, do u really think it might be the problem? becuase i do not feel like bringing it to a mechanic. so would freon r134a be enough to make it work again?

One of my dispatchers has a 2000 Sub and that happens to him too. He does what Liarsenic said. We keep freon in it and it still does it...

so I'm going to have to get the compressor's pressure tested to see what needs to be done, is that correct? or is there like no way to fix it unless i get a whole new air conditioning system in the car, which I do not want to do, because it wouldn't be worth it. I'm probably better off just waiting the few minutes then I guess....

Just pay the 80 dollars to have the problem diagnosed. Then you'll have your answer.

bossesjoe

Don't pay a penny more then $40, if even that. It's a simple process, they just disconnect the feeds and tap into the system with a machine.

Now, if you want someone to run a UV dye though the system, and then starting combing the lines for a leak wearing special glasses and a UV light, it starts to get expensive.

My advice, flush the system, and then test the pressure.

^ Or save yourself time and money, by paying the 80 dollars to have the problem diagnosed at your local Chevy Service Dept.

bossesjoe

I assumed you meant eighty dollars at a non-dealership mechanic, which is too much to diagnose an A/C system.

Why would he have to go to a dealership?

Dealer diagnosis is highly overrated.

I trust the people who run into this same problem day in day out and have fixed it.

I just a little bit of google work and it seems like like a common issue on Suburbans is the clutch mechanism on the A/C compressor. The clutch takes longer to fully catch then most.

If this is the case on your car, you might be looking at a rebuild of the compressor. This is something I wouldn't typically recommend, considering rebuilt auto parts are very high on my list of things to stay away from, but lucky for you it seems you're able to get the full use of you're A/C, just not right away. Knowing that, along with know this history of issues associated with the compressor clutch system, makes me suspect that the only thing wrong with your A/C system is the compressor's clutch. That means the bulk of the machinery in the compressor, the part that usually gets rebuilt, is still working and wouldn't have to be messed with. That's important, because rebuilt compressors, that had the actual compressor unit break, don't last long at all. I'll reiterate, if for any reason someone tries to sell you a rebuilt compressor, don't buy it. Instead, see if they can rebuilt the pulley/clutch unit on yours, or if a replacement pulley/clutch unit is available once you have confirmed the issue. That will mean your A/C system will be gone for a few days, but once it's back you'll know a world of coolness.

thank you very much for the suggestions u guys...very helpful...im going to take them into consideration and see which one is easiest/most convenient for me....or the one that will work that is

That never works. I've gone down that road far to many times. I've replaced far to many parts listening to what others say they did to fix their car. You end up replacing everything, and fixing nothing. That's the expensive route.
The reason I say go to the dealer for diagnosis, is because they specialize in that particular make. If you choose to have them fix it, it may be expensive, but at least you have piece of mind knowing that hte job was done right.
Only Technicians run into the same problems day in and day out. Everyone else runs into them once (if they're lucky).
That's just my opinion though.
