Installation Notes and Tips

Verify the vehicle uses a rear wiper motor before ordering. This unit does not include a washer pump, so transfer or inspect the washer system separately if equipped. If the rear wiper does not park correctly, check crank arm position on the motor shaft and follow the vehicle-specific hidden park reset procedure when applicable. If the washer pump is defective on certain systems, the motor may not operate until that issue is corrected.

Each motor is load tested before release and assembled with the proper lubricant amount to support quiet operation and durability. The upgraded gear material and torque-focused magnet design are intended to improve long-term reliability in demanding rear wiper service.
