Purpose and function of the body window

Mercedes W169 Window Glass AS2 Rear Left N/S serves as a fixed side glazing in the rear part of the body. Located on the driver's side in the rear area, it is responsible for:

• illuminating the rear passenger cabin,
• maintaining the structural rigidity of the side body panel,
• preserving the continuity of the vehicle's styling lines and aerodynamics,
• properly sealing the passenger space against external factors.

The AS2 marking type indicates a window with specific light transmission and safety parameters, compliant with requirements for side windows in modern passenger cars.

Body fitment and installation

The component has been designed specifically for the W169 compact series body, taking into account the characteristic geometry of the rear bodywork. The placement on the vehicle, defined as rear – left side, eliminates the risk of error when selecting the installation side and facilitates service work.

With the correct selection of seals and mounting strips, the window allows for:

• stable seating in the body frame without stress,
• maintaining a seal at the glass-to-body interface,
• preserving factory installation clearances and fitment with adjacent components.

Due to the specific shape and bending radii, installation at a specialized car glass replacement service is recommended, which minimizes the risk of damage during installation.

Performance characteristics and safety

The rear left body window in the W169 model is manufactured as a durable element, resistant to typical operational loads such as body vibrations, temperature changes, or UV radiation. The glass construction ensures:

• adequate rigidity while maintaining the required flexibility in the body frame,
• safe material behavior in the event of damage, in accordance with standards for side windows,
• stable visibility for passengers in the rear of the cabin.

Selecting the correct window for a specific body version is crucial for maintaining the proper field of view and compliance with homologation regulations.

Selection by OEM number and compatibility verification

This component belongs to the Car windows category, where precise fitment to a specific model and body version is key. To ensure that the window will be fully compatible with your vehicle, it is worth verifying it by the OEM number and interchangeable numbers assigned to the specific unit. In practice, the most reliable method is to compare data with the vehicle documentation or information obtained based on the VIN.

Component condition and practical application

The offered window is a used original component, which allows you to combine the preservation of the factory body character with a cost-effective repair. This type of part is particularly suitable in situations of:

• repair after a collision or mechanical damage to the side body section,
• renovation of a vehicle where the existing window has cracked or become dull,
• restoring the full functionality of the car after an unprofessional previous glazing replacement.

Choosing an original, used body window allows you to maintain visual consistency with other body elements and reduce the risk of fitment issues typical of aftermarket replacements with universal geometry.
