Clicking Noise From Behind Center of Dash on Mercedes-Benz C350 4MATIC

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.
