Purpose and function of the mechanism
The front right wiper motor mechanism is responsible for driving and guiding the passenger-side wiper arm. This component transfers torque from the drive to the wiper linkage and axle, ensuring smooth, consistent movement of the blade across the windshield. A properly functioning mechanism directly impacts the driver's visibility in adverse weather conditions and driving safety.
The original design dedicated to the W221 guarantees compatibility with the factory mounting system, working kinematics and range of motion, without the need for modifications or adaptations.
Construction and fit for Mercedes W221
The mechanism is designed specifically for the W221 body, taking into account the characteristic shape of the windshield and the position of the wiper axis. This allows:
- the correct resting position of the arm on the right side is maintained,
- the wiper movement covers the area of the windshield intended by the manufacturer,
- The mounting points match the factory mounting points on the bodywork, making installation easier.
The location on the right side of the vehicle means that the component works with the left side as part of a single system, but is responsible for the independent operation of the right arm in accordance with the control logic used in the Mercedes W221.
