Here's me dilemma.....My A/C stopped blowing cold air. Took it to the shop, they said the cap where you put the freon in was on too tight and was pressing down on the valve, thus causing the freon to leak. No charge. Three weeks later, A/C not blowing cold air again. What could it be? I want to start cheap, as I don't have the money right now to dish out a lot of money. Should I just buy a new compressor? What are my options? Again, I want to start cheap in trying to fix this problem. Any help would be greatly appreciated!
