AC doesn't blow cold on 1993 Oldsmobile Achieva

I refilled my freon in my car with r134 with an r12 attachment. Still doesn't blow cold but the compressor is turning. What could be the problem and/or fix? Thanks for the help.

bad thing you did. you need to remove what freon you installed and the system must be flushed, the accumultor replaced, evacuated and a dye installed to check for leaks. the fittings must be changed to accept the 134 guage set.

Really need to Diagnose this issue. Here is a link to an article that we at RepairPal constructed to help people with A/C problems. Just filling up a faulty system can do harm to it in many cases. Mixing R12 and R-134 is also NOT ever a good idea, ever.
