I just bought a 98 explorer and the air conditioning worked fine for a while. Just today as I was driving to work, it started blowing warm air. It still blows semi-cool air on max cool but not on regular a/c. The compressor is coming on as I checked it. I am praying that it is just a low charge. The previous owner told me that he had never recharged the freon since he bought it new so I am praying that that is all it needs. Any other ideas? Also how do I check the freon levels?
