Purpose and body fitment

The offered window is designed for installation in the rear right part of the estate body, in the passenger door area.

This ensures correct guidance of the window in the tracks and proper cooperation with the lifting mechanism.

AS2 glass characteristics

The side window in the AS2 standard meets the requirements regarding light transmission and mechanical resistance for windows mounted in the side parts of the body. This marking indicates:

• controlled light transmission suitable for side windows,
• safe cracking characteristics of tempered glass,
• adaptation to daily use in varied weather conditions.

Such parameters translate into stable visibility conditions for passengers and compliance with homologation requirements for side windows in passenger vehicles.

Benefits of using an original Mercedes window

The rear right door window dedicated to the Mercedes W203 series estate provides:

• factory fitment to the shape of the door frame and seals,
• proper adhesion to seals, which reduces the risk of noise and leaks,
• compatibility with the standard window lifting mechanism.

The element comes from the Car windows segment, which means it was designed to maintain the appropriate body rigidity within the door opening and proper cooperation with other door components.

Used condition and installation aspects

The product is offered as a used part, which allows for reducing repair costs while maintaining the functionality required for daily operation. Replacing the window in the rear right part of the body is particularly important after mechanical damage, break-ins, or cracks resulting from thermal stress. A correctly selected window allows for restoring full door functionality, including the proper operation of the lowering and lifting mechanism and tightness against water and air.

Support in selection and cost optimization

In the case of used body elements, such as side windows, it is crucial to verify compatibility with the specific body version and vehicle year. It is worth paying attention to the markings on the edge of the glass, the body type (estate), and the positioning on the vehicle to avoid installation problems.
