Help with air conditioning
First off I'll admit I can add freon and that's about the extent of my air conditioning knowledge. My air blows hard and is full of freon but it doesn't cool. Any ideas?

It doesn't need freon, I checked that already. The compressor was working but I Haven't checked it recently. I think I'm going to take the overall advice to take it to an AC shop and have them look at it. Thanks for the help/advice!!!

Last summer my AC was bone chillin cold lol (would joke around with my friend w/ no ac) and now the compressor doesnt even come on! Hot air all the time.. Anyone have any ideas?
I did add a little bit of freon end of the summer so if I over charged it would the compressor not come on at all?

Well I hope you didn't actually add "freon" as these systems are R134a, not R12 like older vehicles. Did you just pick up one of those cans from Wal-Mart? You could have overcharged the system and caused a worse issue than you already had. I would take it somewhere and have an AC shop take a look at it. Let them run a few tests. It might cost you a couple bucks to have them look at it but you won't be wasting money overcharging the system and replacing parts you don't need to.

Man i got so fed up with it I just ripped it out to save the 40lbs it was taking up. When i went to purge it I had NO freon in the system, so mine was probably as simple as just having a leak somewhere. Good luck with it man.

No A/C
You know, I did not check the system itself for Freon. I am use to the compressor at least clicking on/off. It may be since it has a pressure sensor on the system, and if it is empty it will not turn it on. I will check that next! Thanks for the info!

I got a similar issue. My AC system has been topped off with freon as it was low. Now the AC compressor does not even click on and it blows hot air.
Is it possible that the fuse and/or relay may be bad? The car has 102K miles, so the compressor my be bad, but I hope it is a more cost-friendly repair. What should I check first? I doubt the lines are bad, I figured they would have checked those (I got 2 lines I can switch out) so should I just go ahead and replace the fuse, relay and then if that doesnt work, change the lines? Then if all of the above dont work, is it the compressor itself that may need to be replaced?
If so, how many miles is "too much" for a used compressor to have to be considered not a good purchase to replace mine with? Thanks in advance for any help.

Check the wires leading to the compressor itself. I had a situation similar to yours and found that the way GM had routed the wires leading the the AC compressor was such that they were almost flush with the actual pulley on the unit. One day, my ac stopped working and I found that the pulley had actually rubbed through one of the wires. I reconnected them and put a twist cap and some electrical tape on it and that had solved the problem.
