Early last autumn, my a/c stopped blowing cold air. But sometimes, when I recycle the switch it works normally then returns to blowing warm air again. When I brought it to a dealer, they initally said it was working normally and after I told them the problem, they recommended replacing the compressor and clutch for $1200. My a/c has not worked properly since then even during the unusually warm days last December. I waited after winter and got second opinion from independent mechanic who thoroughly checked the fuses, refrigerant and the electrical connection to the compressor. He said the compressor does not look good but said he?s not 100% sure and recommended getting a dealer to check engine computer.
Today in 82 degrees outside temperature, I decided to turn on the a/c; and after months of not working, it blew cold air for quite some time; then it started blowing warm air. After giving it a rest and recycling the switch, it worked just fine. It?s just a matter of time when it will blow warm air again.
I?m hesistant at this point to replace the compressor because it may not be the real culprit. Are there other things I need to consider as possible culprits?
I would appreciate it if anyone can provide some insights/suggestions.
Many thanks in advance.
