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.
Clicking noise behind glovebox when the heat/ac first comes on. Happens periodically when running ac. Also happens when the car is not running, no key in ignition.
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.
Thumping noise from glove compartment area when ac/ht is turned on. Also, noticed after car was turned off.
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?
I hear a knocking sound from the dash when I turn on the heat/AC. Noise only last a few seconds.
Same as others. Knocking sound under glove compartment. Heard that it is the AC compressor and may cost hundreds to repair!
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 knocking loud noise. Whether I'm driving or not or running the AC
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).
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.
i have a loud knocking noise behind my ac uint also
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!
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!!
Knocking sound behind glovebox . Usually when AC/heat is turned on and off . Several knocks then stops .
