   Hi There, Here is the best way to diagnose this problem: Get a long s***w-driver. Turn on the A/C with the motor running. CAREFULLY, place the tip of the long screwdriver on top of the A/C compressor. (the device that is being spun by the belt) Have someone turn on / off the A/C and wait for the infamous moan sound. Put your ear to the other end of the screwdriver, and if you hear a lound whine, you know that it's time for a new compressor. (you will hear it clear as day, just like a stethoscope!) If you are uncomfortable around the engine, by no means try this. If you have a general knowledge of what parts are moving, don't have a necktie on, have a steady hand, excersize common sense and caution, and you will have no troubles. ------------------- If this is where the sound is coming from: 1) Have your refrigerant level checked first, you may luck out, and just need a slight charge. 2) If refrigerant is OK, you are going to have to have the compressor serviced or replaced. If this is not where the sound is coming from: 1) Have someone operate the A/C (on/off) and see if the belt is slipping when the engine is running. If so, the belt simply needs to be replaced. Hope it helps
