Product Details

Cardone’s Windshield Wiper Motor line is built from decades of remanufacturing and reverse-engineering experience, then refined as a new replacement design. The goal is to improve durability where original motors commonly wear out, especially in the gear train and torque delivery system. Part number 85-3400 is a front wiper motor for Mercedes-Benz models including the E320, E430, CLK430, and related applications listed below.

This part cross-references Mercedes-Benz 2108201742 for the same application.

Common Problems This Part Can Help Solve

• Wipers stop in the middle of the windshield
• Wipers do not park at the bottom of the glass
• Slow, weak, or intermittent wiper movement
• Grinding, stripping, or gear noise from the motor
• Failure after washer pump-related electrical issues are diagnosed

Installation Notes and Tips

Before replacing the motor, confirm the washer pump is functioning, since some Mercedes-Benz wiper systems will not operate if the washer pump has failed. If the vehicle does not use hidden wiper blades, parking misalignment is often corrected by adjusting the crank arm position on the motor shaft. Refer to the vehicle service manual for the hidden-park reset procedure when applicable.
