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.

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

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!

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.
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.
same issue.. but I replaced the cabin air filter and my problem went away.. it's on you tube. very easy to replace! try this first!!
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.

Bought the car at this mileage and not even two days later the A/C compressor goes out. It would make a horrible metal grinding/ knocking noise when I'm idle but going down the road it would stop til I stopped again. But the next day it just stopped working, I'm just driving down the road and I went it turn off cuz u can feel the load on the engine when it's on and hot air started coming out and that's it

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
