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.

terrible knocking and clatter from front of engine compartment. replaced all pulleys and tentioners, new power steering pump, new alternator, NOW they are telling me in the aC compressor. Is this a common preoblem with the 08 avenger?

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!

Well we havent fixed it yet,but when we turn on the heater or ac it starts knocking for about 15sec an it goes away. Sometimes it even knocks when the car aint even on.

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.

The car will not shift all the time and they said there was nothing wrong with it. They put a moniter on it but lost the first reading and got a second reading but didn't say what it was but wanted to leave it on and when it didn't shift press the button. Sounds crazy to me, this is a 2013 dodge avenger. This did this last week and again on Fri the 24th. Is there a recall on this car? Not of the correct mileage, it's at 29,000 now

Just bought a used 2012 Avenger from a dealership. Heard the knocking/clucking noise when driving it home and even when the car was off and no key in ignition. Took it back to the dealer and after having it checked out they reported Dodge techs said this was normal, just a fan relieving pressure. It's 6 months later and it's getting worse. I don't think this is normal b

Started knocking, but when turned on the recirc. it stopped, but now it does it all the time, only last 5 sec. but getting louder, not about to pay the dealer an arm and leg, will trade it in before I pay them another dime for being idiots.
I get the knocking noise after the air conditioner is turned on and it comes back even when the engine is not running.
