2003 Mercedes-Benz C320 ProblemsBroken Stepper Motor Actuating Arm May Cause Clicking Noise From Behind Dash
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.
The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.
The electrical connector at the automatic transmission may leak fluid. Over time leaking fluid could migrate through the wiring harness and damage the transmission control module. If that happens a new harness and control module may be necessary to correct the problem.
