Dodge Avenger Knocking Noise From the AC Compressor

(90 reports)

A knocking sound my be heard from the engine at times with the air conditioning on. The cause could be the AC compressor itself, if that is the case there is an updated AC compressor to correct this issue.

I hear a knocking noise that seems to be coming from the under the glove compartment. I only hear it when i turn on the air conditioner. So frustrating since i just replaced the alternator, pulleys and serpentine belt. What else is going to go wrong with this car....its only 4yrs old. -

When the a/c is on it is fine. A loud knocking noise starts when you turn on the recirculate button on the a/c. Eventually it will quit. Sometimes it makes this noise when the a/c is turned off. Turn it on and it quits. -
