I have a 2003 town and country, 3.8L AWD. It has loud rattling noise coming from under the hood on the passenger side. I have had the water pump and serpetine belt replaced. I feel that it may be coming from the alternator. I dont hear it as much when it is at idle with the ac off. it is very loud when the a/c is on and in gear. I would appreciate any expertise on this and instructions on how to fix it.

I had a very similar noise based on your description. It turned out to be the AC compressor starting to fail. It completely gave out right at the tail end of the really hot weather we had this past summer. With the brakes, suspension, tires, transfer case, and exhaust that all went bad since the last inspection, I didn't even bother fixing the AC, or anything else. Repair cost was more than what I owed, so I just traded it in.
