A.C. worked fine last year but nothing now. I tried putting in refrigerant but it never cooled off after 48 oz. I turn it on now you hear what sounds like a vac. sound coming from in the dash after I put in the refrigerant. Compresser is turning on.
No A.C. on 2001 Pontiac Montana

I need to know how much it would cost me to fix the a/c
what does it mean when the a/c is blowing hot air.
