AC not blowing cold

[StadiumArcadium]

I'm having a problem with my AC. The car was retrofitted over in 2003. Since then, I've had to recharge it twice. Both times it was because of a schrader valve leak. That valve is now fixed.

I noticed a while ago that it didn't blow as cold as it used to, now it just blows hot air. We took a pressure measurement, and it's still full. So there is R134a in the system.

Any ideas?


EDIT** This is on my 1993 MTX

Your compressor clutch probably needs to be adjusted, a search here will yeild you with plenty of info about it and how to do it.

First things first. It's a quick check to see if the clutch is engaging or not with the A/C on. Just pop the hood.
