Purpose and Vehicle Placement

The presented body window is designed for installation in the right rear area of the body, within the passenger door. The appropriate profiling of the edges and compatibility with factory seals allow for maintaining the interior's airtightness and proper acoustics. This element works with factory guides and mountings, which facilitates installation in a service or body shop.

Technical Characteristics of the Window

The right rear door window in the Mercedes W205 is an integral part of the side body structure, contributing to passive safety and driving comfort. The construction is adapted to work with the factory window lifting system, maintaining correct pressure against the seals and door frame. This limits unwanted wind noise and the risk of moisture ingress into the interior.

Its original Mercedes origin promotes dimensional compatibility with other body panels, which is particularly important for post-accident repairs and precise door alignment with the body.

Application in Body Repairs and Servicing

This part is ideal for professional body repairs when window replacement is necessary due to mechanical damage or during a comprehensive renovation of the vehicle's side section. By maintaining factory specifications, you can:

• restore the correct glazing geometry in the right rear door,
• maintain a consistent appearance of the side window line,
• reduce fitting time during installation.

This solution is particularly beneficial for workshops that expect a predictable installation process and stable build quality.

Used Condition – Practical Benefits

The window is offered in used condition, which significantly reduces repair costs while maintaining the original origin of the part. For many users and repair shops, this is a reasonable compromise between budget and quality, especially for body parts that must be dimensionally compatible with the vehicle's factory construction.

This includes the mounting method as well as cooperation with door seals and hardware. Therefore, the window can be safely used in repairs where restoring the vehicle's original parameters is crucial.
