Purpose and Fitment for Mercedes Vito / Viano W639

The presented left rear side window has been specifically designed for Mercedes Vito and Mercedes Viano models of the W639 generation. Its placement in the vehicle is the rear on the driver's side, allowing for precise fitting into the factory mounting opening and maintaining the correct body line.

The original design of the window ensures compatibility with the factory body geometry, which simplifies installation and reduces the risk of leaks. Consequently, this part is well-suited for both bodywork and paint repairs, as well as for replacing worn or scratched glazing.

Technical Specifications of AS2 Side Window

This window belongs to the AS2 classification, which translates to an appropriate level of light transmission and compliance with homologation requirements for side windows in passenger and commercial vehicles. This type of glass is designed for safe shattering in the event of a collision and for proper visibility for passengers.

This solution is particularly important in commercial vehicles like the Mercedes Vito and Viano, where side windows serve to illuminate the passenger or cargo area and ensure adequate visibility during maneuvers.

Application in Body Repairs and Upgrades

The used left rear side window is a practical choice for:

• replacing a window after mechanical damage or cracking,
• post-accident repairs of the rear body section,
• converting the interior from a cargo to a passenger version,
• completing missing glazing elements after disassembly.

By retaining its factory shape and dimensions, the window allows for the restoration of the vehicle's original functionality without the need for body structure modifications. This solution facilitates the work of body shops and services specializing in bus conversions.

Used Condition and Economic Benefits

The part is offered in a used condition, which significantly reduces repair costs compared to purchasing a new window while maintaining its original origin. For many Mercedes Vito and Viano users, this represents a sensible compromise between quality and budget, especially for major body repairs.

Choosing an original used side window minimizes the risk of fitment issues common with cheaper aftermarket alternatives, while also helping to maintain the vehicle's consistent appearance.

Selection by OEM Number and Purchase Support

When selecting windows for specific body versions and model years, using the OEM number and interchangeable part numbers is particularly helpful. To simplify the verification process, consult the practical guide – you can find it in the article Guide: How to Select the Correct Car Part by VIN and OEM Number, which describes step-by-step how to check part compatibility with a specific vehicle.
