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.

Knocking noise happens after I turn off the heat or air conditioning... Goes away after a few knocks but is annoying and load when it happens ...

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.

I get a loud knocking noise when I turn the A/C and or heat on or off. It knocks/clicks for less than a min, but is very annoying. I have not brought it in to a shop yet to see what the problem is.

Clicking sound from the passenger side dashboard. Occurs when car is first started and A/C or heat is on, and lasts for a few seconds. Will stop immediately if A/C or heat is turned off. Also notice this when car is parked in garage, even after not running for hours.

When the ignition is turned on knocking can be heard from behind the glove box. The knocking lasts for less than a minute then stops. This just recently started.

There is a loud knocking sound that seems to come from behind the glove box occasionally when I turn on the AC. Could it be the compressor? The sound comes and goes.

Same as others. Knocking sound under glove compartment. Heard that it is the AC compressor and may cost hundreds to repair!

Noises from the engine were heard, took the car to Dodge tecnician and was advised that A/C Compressor was damaged. Estimated cost of repair was $ 800.00!

Knocks exactly 23 times whenever electrical system comes on AND A/C is turned all the way down. If it is one notch to the right, knocking does not occur. But if it is turned all the way left, it occurs when I simply open the door (presumably turning the electrical system on).
