Application and fitment for Mercedes Vito / Viano W639

The offered glass is intended for installation in the rear left sliding door of Mercedes Vito and Mercedes Viano W639 generation models. The glass construction is adapted to the factory mounting opening, which allows for maintaining the original body geometry and the correct operation of the sliding door mechanism.

Thanks to this component, it is possible to both replace a damaged window after a collision or crack, and to restore full functionality and tightness of the side body section without the need for using replacement solutions of uncertain origin.

Technical characteristics of AS3 tinted glass

Glass marked with the AS3 class is a tinted window intended for areas other than the driver's field of vision, which allows for the use of darker tinting. In practice, this translates into:

• increased protection against the vehicle interior heating up,
• reduction of glare and improved travel comfort for rear passengers,
• better protection of transported cargo from the view of unauthorized persons,
• a consistent, aesthetic appearance of the side body section in versions with factory tinting.

Tinted glass in this configuration works well both in passenger vehicles and in shuttle, taxi, or service bus conversions, where combining functionality with user comfort is important.

Benefits of using an original used window

The original dismantled window retains factory fitment parameters, ensuring that the body line, gaps, and seal performance remain consistent with the manufacturer's specifications. This is especially important in sliding doors, where an incorrect shape or glass thickness can cause closing problems or leaks.

Choosing an OEM used component allows for reducing repair costs while maintaining the quality characteristic of the Mercedes brand. The window is suitable for re-installation after properly preparing the mounting area and using the correct installation materials.

Selection by OEM number and purchase support

To ensure full compatibility with a specific equipment version and vehicle year, it is worth verifying the window's compliance using the OEM number or interchangeable numbers. The vehicle's VIN number and comparing the sliding door configuration (left side, rear, tinted sliding window) will be helpful in the selection process.
