Purpose and function in the wiper system

The presented arm is dedicated to the rear window of the Mercedes-Benz A-Class W169 generation and operates in the trunk lid area. Its task is to precisely press the blade against the glass surface, evenly distribute pressure, and ensure stable operation across the full range of the wiper's movement. Thanks to this, the rear window cleaning system maintains proper efficiency both during rainfall and in road dirt conditions.

Construction and fitment for the Mercedes-Benz A-Class W169

The arm has been designed specifically for the geometry of the rear window and trunk lid of the Mercedes-Benz A-Class W169, which ensures the correct operating angle and appropriate blade pressure. The design provides compatible mounting to the wiper mechanism axis, which facilitates installation and reduces the risk of improper alignment. The applied design solutions minimize vibrations during operation, which improves the system's performance and reduces noise.

Performance characteristics and installation benefits

The rear window wiper arm in this model is responsible for maintaining constant contact between the blade and the glass, which is particularly important at higher speeds and during heavy rainfall. Properly matching the component to the specific vehicle model reduces blade wear, decreases the risk of streaking, and improves driving comfort. The used nature of the part allows for an economical replacement while maintaining the original mounting specifications provided by the vehicle manufacturer.

Professional selection and vehicle integration

Selecting an original rear window wiper arm is important for the proper operation of the entire wiper system. This component works with the drive mechanism and the blade, so its geometry and mounting method must be consistent with the factory solution. A properly selected arm reduces the load on the mechanism, which can translate into a longer service life of the drive and stable operation over a longer period of use.
