Mercedes-Benz C320 4MATIC Problem
Average Mileage: 110,203 mi (100,000 mi - 119,500 mi)
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.
