2000 Mitsubishi Montero Sport Question: air conditioner squealing



mikesgal06, Chesapeake, VA, July 16, 2009, 13:55

My air conditioner has started to produce a loud squealing noise when turned on. Running the fan alone does not cause the noise. What's the cause?

    It likely to be related to the AC drive belt. That would be the first thing to check. An old belt can produce a squealing noise.

    Could be something as simple as the a/c belt out of adjustment. Worst case scenario probably would be the a/c compressor clutch or the compressor itself going bad, which is somewhat common on these.
