Purpose and function in the vehicle

The rear window washer is responsible for evenly distributing fluid across the glass surface, which allows for effective debris removal by the wiper. This component is mounted in the rear part of the body, in the immediate vicinity of the window, ensuring the system operates stably and predictably.

A properly selected nozzle reduces fluid consumption while allowing for quick window cleaning, which is important for both driving comfort and safety.

Design and compatibility with the washer system

The washer is part of the Washer fluid reservoirs, pumps, and nozzles group, working with the existing hose installation and fluid pump. The design provided by the vehicle manufacturer ensures:

• proper sealing at the mounting point,
• a stable connection to the fluid supply hose,
• a properly shaped spray pattern on the rear window.

By using a solution consistent with factory specifications, compatibility with the washer system and proper cooperation with the rear wiper are maintained.

Performance characteristics and advantages

As a component from a Mercedes vehicle, the rear window washer has been designed for long-term, stable operation. Key benefits include:

• maintaining the factory spray geometry, which improves visibility in rain, snow, and while driving on dirty roads,
• consistency with the existing mounting system in the tailgate,
• the ability to restore proper washer system operation without interfering with the vehicle's electrical installation.

Replacing a worn or clogged nozzle with a functional part helps reduce the risk of streaks on the glass, uneven fluid distribution, and issues with wiper performance.

Component condition and service application

The offered washer is a used part, which is a cost-effective service solution for users looking for original components at a reasonable price. Such elements are commonly used in workshops for maintenance repairs when maintaining consistency with the vehicle's factory design is a priority.

In practice, installation involves removing the old nozzle, connecting the fluid hose, and seating the component in the prepared mounting hole, which reduces vehicle downtime.

Technical support and part selection

When selecting a rear window washer, it is worth using the manufacturer's markings and vehicle data to ensure full compatibility with the washer system. Proper fitment translates into the correct operation of the entire system and reduces the risk of leaks or incorrect spraying.
