Purpose and function of the component

The rear left window sealing strip in the BMW Cabrio E88 is responsible for the stable guidance of the window in the channel and for limiting the ingress of water and debris into the door interior and cabin. A correctly selected component for the appropriate side of the vehicle allows for maintaining the body line and proper adhesion of the window to the roof and other side windows.

Thanks to its dedicated placement on the vehicle, the component works with the factory window mechanism, which minimizes the risk of jamming, rattling, and leaks during opening and closing. This is particularly important in a convertible, where the window system is an integral part of the sealing system for the entire passenger compartment.

Benefits of using an original sealing strip

• maintaining the factory fit of the window with the frame and roof,
• reduction of wind noise at higher speeds,

• stable operation of the window lifting mechanism over a long service life.

For users who care about the condition of the bodywork and the acoustic comfort of their convertible, this is a solution that allows for a technically correct repair without compromises in terms of fitment.

Application in service and body repairs

The rear left window sealing strip is used both for the typical replacement of a worn component and for more extensive body and paint work in the rear part of the vehicle. It is particularly useful when:

• leaks appear in the area of the rear left window,
• the window operates with resistance or makes unwanted noises,
• it is necessary to restore proper window guidance after body repairs.

Selecting parts by OEM number or interchangeable numbers ensures that the component will be compatible with the specific vehicle configuration.
