Get a bottle with the gauge on it at advance or where ever you go. Turn the car on, put a/c to max, let it run for a few secs, connect the hose with the gauge and R-134A to the spout in the pic (take the black cap off it obviously) and see where your level is at. You want it to be in the blue range, depending on which brand bottle you buy. Cost is like $20-30 for the stuff. If it is low and after you start filling it, it leaks out, you can check for the leak with a uv/black light and we sell an r134a additive to help you find where its seeping out of.

Could be the compressor going out. The compressor has small pistons, alot of times you get blow-by ( loss of pressure) and it won't blow cold at low RPM's. Thats a common problem on R4's...gm crap.

If there is a cracked or a hole in one hose that will definantly be a problem. I was going through this in my 96 GT. I thought it needed to be recharged so i did it. Come to find out it never got cold so I BOUGHT the recharge kit with the red dye in it to detect a leak in a line. Sure enough I saw red dye coming out of the house back by the firewall and it cost me a pocket wrenching 85 cents for a new vacum hose. Listen to your car if you here air coming from somewhere sorta like a hissing sound check your lines. Hope this helps.
