2003 Monte Carlo SS AC not blowing cold air. Any suggestions or has anybody else had that problem before?

 

Do you have a gauge you can use on the freon port to see pressure? That'll tell you if the system has freon in it. If you don't have one the local auto parts store might have one in a loan a tool capacity you could use.

 

I don't have one I'll check see if AutoZone or somewhere for a loan on one
