Have a problem with my A/C in 03 LS

Alright guys, I have a pretty bad issue that pisses me off. I live in Maryland and well, when its spring/summer, it gets hot! Here's my problem, the A/C works, but no cold air comes out. It blows air no problem and when you switch the modes like vent to defrost and etc, it works completely fine. There's just not any cold air that comes out. I tried recharging it and it blew a little cool air, but i think it might be out for good. I also checked all fuses and relays and there fine, the compressor turns on no problem, and etc. I hope someone could help me out, thanks.
