Mercedes-Benz C320 Clicking Noise From Behind Center of Dash

(100 reports)

A repetitive clicking noise from behind the center area of the dash panel is usually caused by a broken stepper motor actuating arm. The actuating arm controls the direction of air flow in the climate control system. Disassembly of the center console will be required to access and change the broken arm with the updated, reinforced part.

Once I start the car, I hear a clicking noise from the behind the dash. When it started it was only about 45 seconds, now it is going on for about 1 1/2 minutes to 3 minutes. Now I hear at least two motors clicking. It affects the AC and the Heater function, to the point that the AC will run by itself when turned off, Half my windshield will not defrost (Passenger side) and I believe it has affect the entire AC system. -

Everytime I start my car there is a very audible clicking noise from behind my dash. Sometimes when it is very cold there is not a noise. And when there isn't a noise, the heat doesn't work. -
I also had this problem along with several others started to appear right after the 100,000 mark on mileage. I have had several major issues for different failures like major oil leak that created failure of three/3 out of six cylinders (cost $2500), left seat control module two times (cost >$1200 every time), ESD failure (cost $2000), that locked my steering wheel, fuel pump and filter failure (cost $1200), two other reoccurring issues that are hard to explain and so on... like I can never get rid of light lamp/bulb failure signs even after I have replaced many of them over time. I don't think Mercedes even care about users' concerns any more. I think they are trying to get into car service business instead of selling reputed reliable cars. -

Broken stepper motor arm. To expensive to replace -
Loud clicking sound every time car is started from right behind the dashboard, which continues for a couple of minutes and then goes away until the next time the car is started. -
My C320 is a 2001, with all sorts of issues, clicking noise under hood near front of car, car shakes when stopped at a light, feels like spark plugs, which I just replaced, may be malfunctioning, check engine light comes on periodically and stays on while driving, lamp lights are always needing to be replaced, air conditioner doesn't work properly most of the time, had to unplug passenger front seat due to draining of battery, but I heard its dangerous to drive without the seat plugged in due to the fact that the air bag will not deploy on that side if you are in an accident, can't believe this expensive car is such a lemon. I'm not happy and would not recommend this vehicle to anyone, nor buy another one. -
repetitive noise from behind the dash. had the same issue with a ford windstar van so I am sure it is a damper actuator that is thumping. have not repaired it yet. -
