Purpose and Function of the Seal

The presented seal is designed for installation in the rear left door area, where it is responsible for properly sealing the window and the window-to-door contact. Proper fit in this location is crucial for:

• reducing air drafts at higher speeds,
• minimizing road noise and wind noise,
• protecting the door interior from water and small debris,
• ensuring stable operation of the window lifting mechanism.

Thanks to its design, consistent with solutions used by Mercedes, the seal works with the factory door frame and window guides, promoting proper geometry and smooth window movement.

Technical Characteristics and Installation

This element belongs to the Window Seals and Trim group, meaning it is designed for direct contact with the window and the door edge. The seal's profile is adapted to the body shape of the GL X164 series, facilitating installation and allowing for even pressure along its entire length.

The placement on the vehicle, identified as the rear left side of the body, allows for unambiguous identification of the mounting position and avoids errors in part selection. In practice, this translates to:

• seamless integration with the factory door frame,
• proper adhesion to the window throughout its range of operation,
• maintaining the passenger cabin's seal as designed by the manufacturer.

Benefits of Using an Original Seal

Using a seal dedicated to a specific body model reduces the risk of leaks common with universal aftermarket alternatives. A well-chosen seal:

• helps maintain stable acoustic comfort inside the cabin,
• reduces the risk of window fogging by improving moisture drainage around the frame,
• supports the durability of the window lifting mechanism through proper glass guidance.

For GL X164 class vehicles, where both driving comfort and resistance to intensive use are important, a properly selected door window seal is a crucial element for maintaining the proper standard of usability.

Component Condition and Service Application

The offered seal is a part from the Mercedes group, intended for service applications when replacing worn or leaking elements in the rear left door. It is suitable for standard repairs due to wear and tear, as well as for bodywork and painting after damage to the side of the vehicle.

Selecting the correct seal for a specific GL X164 model helps reduce the need for additional window adjustments and minimizes the risk of having to remove the door trim again shortly after the repair.
