   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
