If all the refrigerant has leaked out of it and moisture has gotten into the system, then, many parts will have to be replaced.

What makes you so sure that "the compressor works fine"?

Im not really sure the compressor works fine actually. I am just going by the fact that its not froze up. Is there a test I could do to make sure the compressor works fine. And in your opinion is replacing air conditioning parts on a truck that old worth it at all. Just asking your opinion is all..Well thanks in advance for your help...Andy

I guess you have to answer that. How much is it worth to you to be cool in the summer?

I wonder how much real diagnosis your transmission guy gave you, or if he just quoted how much it would cost to replace parts. The only way to really know what is wrong with it is to take it to someone qualified to work on air conditioning systems, let them put the gauges on it, and see what's left in it (if anything).

If you find a "buddy" who is willing to break the law, he can charge it with R12 for you, and it might get you by for a while assuming it is low on refrigerant.

Maybe you should be more specific about how & when it stopped working. Did it gradually lose it's cooling? Does the fan work? etc. It might not be a problem with the A/C at all.

Hi Dave yes the fan works fine doesn't really blow that much air, as it used to be. I have wondered before if it might be a problem with the controls even. Like the blend door I have heard about that a really simple fix. Do you know anything about that at all. You have a great day today ok Dave....Andy

It certainly could be. Perhaps if you give more details here, what works, what doesn't, what the symptoms are, etc. someone who is an expert in a/c systems will be able to help you.

Otherwise, you should take it to someone who knows how to work on A/C systems.

It is common for the compressor to fail first, so it may not be fine.

The most common thing is for the Freon to leak out slowly over time, at a point the low pressure switch shuts down the system to prevent it from burning itself out. Have a competent shop evacuate and reclaim any remaining Freon, and pull vacuum on the system, and see if it'll hold vacuum, 28-30 in. lbs, for 20-30 mins or so. If it holds the vacuum, then have them charge it. It may work fine. If not, they can reclaim the Freon, and diagnose the system for you. Swapping the system over to R-134A is not very expensive, but your truck may already be set up for it. I don't know what year that truck switched from the factory.

By the way, the compressor isn't the real expensive item, the condenser and evaporator are much more than that, but the big expense is labor to replace 'em.
