Purpose and vehicle placement

The presented window is designed for installation in the rear area, on the left side of the body. As a side "quarter" glass component, it works in a fixed connection with the body frame, responsible for:

• maintaining the correct geometry of the glazing in the rear part of the vehicle,
• completing the side body line on the driver's side,
• providing proper illumination of the rear cabin interior.

Placement in the rear left part of the vehicle requires precise fitting to the body profile, which is why using an original window dedicated to the C140 body is crucial for maintaining tightness and aesthetics.

Technical characteristics of the AS2 glass

The glass marked with the AS2 class meets the requirements for light transmission and safety in the side body zones. The appropriate glass structure ensures:

• controlled light transmission, adapted for use in rear side windows,
• adequate resistance to stresses resulting from bodywork operation,
• safe material behavior in the event of mechanical damage.

Thanks to the factory edge profile, the glass works with original seals and mounting strips, which facilitates correct installation and reduces the risk of leaks.

Benefits of using an original Mercedes window

Using an original Mercedes component in the rear left part of the body allows you to maintain visual and technical consistency with the rest of the vehicle's windows. The main advantages include:

• factory fitment to the C140 body – no need for modifications or shape adjustments,
• maintaining uniform glass optics relative to other windows,
• compatibility with original mounting points and trim elements.

The used OEM component is a sensible choice for post-accident repairs or replacing a damaged window when the priority is combining quality with cost control.

Application in body and glass repairs

The rear left quarter window is particularly suitable for repairs of the side body after collisions, parking damage, or replacement of corroded frame elements. Replacing this component is important when:

• the glass in the rear left section has cracked or shattered,
• reconstruction of the side glazing is necessary after bodywork,
• leaks or optical distortions appear in the rear side window area.

Selecting the correct window for a specific body type helps avoid problems with fitment, wind noise while driving, and improper seal adhesion.

Compatibility, identification, and part selection

The element belongs to the Car Windows group and is intended for Mercedes vehicles with the C140 body. When selecting, it is worth paying attention to compatibility with the body version and the mounting side (rear, left side) to ensure full compatibility with the window frame and interior trim elements.

In the case of extensive rear body repairs involving the replacement of several side windows, it is beneficial to collect elements from the same production series, which helps maintain a consistent glass shade and uniform performance of the entire glazing system.
