AC repair questions

[jsbihn]

Ok, well the AC is out on the truck.
I went and had it charged, and within a half and hour if that (without the truck even running) it was completely gone.

I talked to one guy, and site unseen, he said it was the compressor. He stated that the GM compressors were known to leak and leak bad (weird, my 99 Vette hasnt had one problem).

Ok, so I am pretty handy with a tool and was wondering how hard it is to do an AC fix. I was wondering if there was any step by step guides or something to help me diagnose the issue and fix it.

If it is the compressor I am wondering, if reman'd units are any good and if so where is the best place to buy them? I have seen them for 150-300 bucks, where a new one is 500-700.

Thanks in advance
