Mercedes-Benz CLK320 Problems

Clicking Noise From Behind Center of Dash on Mercedes-Benz CLK320

Problem Description and Possible Solution

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.

My car began making the clicking sound from under the dash on the driver's side a few days ago. I've read that the entire dash needs to be disassembled to replace the broken actuator arm in the heater box, which requires about 8 hours of labor. As long as the dash is apart, they advised replacing the same part on the passenger side too.
The ticking sound really get in my nerves! My local mechanics just cant find the problem or where to start !
