I have had an ongoing problem with the air conditioning not turning on. The cabin fan blows normally, but it appears that the compressor doesn't always kick in. When it does, it cools fine. I've had mechanics work on it with no success. I've blown a fuse a few times, and the dealer replaced it with a 40 amp because of a service bulletin. I've had the electric fan clutch replaced supposedly because it was very weak and may not be removing the heat properly. I've also had the control module inside the cabin replaced, again with no success. A knowledgeable friend of mine thinks that I have a ground wire loose, which may be causing my intermittent problem. Has anybody already seen and conquered this problem?
