Mercedes-Benz W203 W209 Front Wiper Motor A2038200442 - Used Original Parts

Diagnosis and Common Symptoms

In the W203 C-Class and W209 CLK-Class chassis, the front wiper motor is directly managed by the Front SAM (Signal and Actuation Module). When the internal gearing of the motor strips or the electrical windings begin to degrade, the most immediate symptom is erratic wiper arm movement. You may experience sluggish operation even on the highest speed setting, intermittent pausing mid-sweep, or wipers that completely fail to return to their designated parking position at the base of the windshield. A total failure will result in zero movement, often accompanied by a rapid clicking sound from the wiper relay in the engine bay. Diagnostic scans utilizing XENTRY or a professional scan tool will frequently log fault codes in the Front SAM, such as B1068, B1069, or B1701, indicating a short circuit, open circuit, or communication breakdown within the wiper motor circuit. Water intrusion into the cowl area is a primary catalyst for these failures.
