Purpose and vehicle placement

The presented seal is designed for installation in the rear left area of the body, within the door frame and window guide. The component works in direct contact with the side window, stabilizing its movement and limiting the ingress of moisture into the door interior and passenger cabin.

This placement means the seal has a significant impact on:

• the tightness of the connection between the window and the door frame,
• the suppression of wind noise while driving,
• the protection of the window lifting mechanism against dirt.

Construction and technical function

The Ford Mondeo IV Door Window Weatherstrip Gasket Seal Rear Left N/S has been designed as a profile matched to the shape of the door frame, with a properly formed edge that interacts with the window. The appropriate stiffness and flexibility of the material allow for secure seating in the slot and maintenance of tightness throughout the entire range of window operation.

Key tasks of this component include:

• creating a barrier against rainwater and contaminants,
• reducing vibrations and rattling of the window in extreme positions,
• stabilizing the vertical guidance of the window, which promotes smooth operation of the lifting mechanism.

Thanks to the preservation of the factory profile, the seal works with other door components, such as internal soundproofing or trim, which translates into more comfortable acoustic conditions inside the vehicle.

Benefits of using an original Ford seal

Using an original Ford Mondeo IV Door Window Weatherstrip Gasket Seal Rear Left N/S allows you to maintain tightness and comfort parameters close to factory specifications. The component has been developed for a specific body model, which means it:

• fits factory mounting points without the need for modifications,
• maintains the correct contact line with the window and door frame,
• reduces the risk of leaks typical of universal profile replacements.

This solution is particularly beneficial for eliminating problems such as wind noise at higher speeds, dampness of the door upholstery, or accelerated wear of the window lifting mechanism.

Characteristics of the used component

The seal comes from dismantling, which means it is a used component that retains the functionality intended by the manufacturer. Such components are often chosen for maintenance repairs when the priority is to maintain the original construction at reasonable service costs.

In the case of door seals, it is important that the profile is not deformed and that the edges interacting with the window and door frame retain their proper shape. A used original component often fits better into the existing body geometry than a replacement with a simplified construction.

Support with selection and additional information

When selecting a Ford Mondeo IV Door Window Weatherstrip Gasket Seal Rear Left N/S, it is worth paying attention to compatibility with the body version and placement on the vehicle. In case of doubt, manufacturer markings and technical parameters assigned to a specific unit, such as SKU, OEM part number, or interchangeable numbers presented in the specification section, may be helpful.
