Intended Use and Fitment for Mercedes W204

The presented wiper arm has been specifically designed for Mercedes W204 series models, taking into account the structural requirements of the windshield and the wiper mechanism. The component is mounted on the front axle on the left side, allowing for correct blade guidance relative to the windshield's curvature and the factory operating path.

Thanks to a design consistent with the solutions used by the vehicle manufacturer, the arm works with the original drive mechanism and blade mount, without the need for modifications or adaptations. This precise fit minimizes the risk of vibrations, uneven pressure, and accelerated blade wear.

Wiper Arm Construction

The windshield wiper arm in the Mercedes W204 is responsible for transferring motion from the drive mechanism to the blade, as well as maintaining stable pressure against the glass surface. The arm's geometry ensures:

• the correct working angle relative to the windshield,
• even blade pressure along its entire length,
• smooth movement along the arc dictated by the windshield's shape.

The appropriately selected arm profile minimizes blade lift-off at higher speeds and reduces noise during operation, contributing to the vehicle's user comfort.

Characteristics of a Used Part

The offered wiper arm is a used part, sourced from disassembly. This type of component is a good choice when the existing arm has suffered mechanical damage, deformation, or wear due to use. A properly selected used part allows for the restoration of the wiper system's correct operation while maintaining a favorable cost-to-functionality ratio.

Before installation, a standard check of the mount and the condition of the pressure spring is recommended, as well as correct positioning of the arm's rest position relative to the windshield. Proper adjustment directly impacts the efficiency of clearing the driver's field of vision.

Benefits of Using an Original Wiper Arm

Using a dedicated wiper arm for the Mercedes W204 offers a number of practical benefits:

• Factory Fitment – compatibility with the windshield geometry and wiper mechanism, without the need for modifications.
