Purpose and Function in the Vehicle

The presented mechanism belongs to the Wiper Motors and Linkages group and is designed for operation on the windshield. The assembly is responsible for transferring torque from the motor to the wiper arms, maintaining the correct angle, range, and synchronization of wiper blade movement, which translates to clear visibility for the driver and driving safety in rain and snow.

The system is mounted in the cowl area, where it works with wiper arms and blades, as well as the vehicle's electrical system. Thanks to its factory design for the W205 and W213 series, compatibility with factory controls and driver assistance systems is maintained.

Assembly Construction: Motor and Levers

The mechanism combines an electric drive and a lever system in one unit. The motor is responsible for generating torque, while the linkage and joint system converts rotational motion into the reciprocating motion of the wiper arms. This solution ensures:

• stable, repeatable wiper blade path on the glass,
• appropriate speed and smoothness of movement in available operating modes,
• maintenance of factory end-stop angles, minimizing blind spots on the windshield.

The original Mercedes design limits the risk of excessive play in the joints, which is important for even pressure of the wiper blades on the glass and noise reduction during operation.

Benefits of Using an Original Mechanism

Using the original wiper motor and linkage assembly in a Mercedes W205 / W213 allows for the preservation of operating parameters as intended by the vehicle manufacturer. In practice, this means:

• correct cooperation with factory control units and sensors,
• proper positioning of the arms in the rest position,
• reduced risk of system overload during intensive use.

For the user, this translates to predictable wiper operation, which is particularly important when driving at higher speeds and in difficult weather conditions.

Condition, Selection, and Practical Application

The part is a used component intended for reinstallation in compatible Mercedes models. Proper selection is facilitated by the OEM marking and available replacement numbers, which allow for matching the mechanism to a specific body version and equipment. If in doubt, it is advisable to verify compatibility by part number or by comparing the construction with the currently installed assembly.

Expanding the Wiper System in a Mercedes

If you are planning a comprehensive repair or upgrade of the windshield area in your Mercedes and need other parts from the same group, such as additional mechanisms, motors, or wiper linkages, check the available parts in the Mercedes Wiper Motors and Linkages category.

This approach allows for simultaneously refreshing the entire system responsible for cleaning the windshield, reducing the risk of subsequent leaks in the cowl area, and ensuring consistency of the applied components from a single manufacturer.
