Purpose and function of the component

The weatherstrip is mounted on the rear left door and works directly with the side window. Its tasks include:

• mechanically wiping water from the window surface during raising and lowering,
• limiting the ingress of dirt and small particles into the door interior,
• stabilizing the window edge in the guide, which reduces vibration while driving,
• supporting the seals in terms of protection against noise and wind gusts.

By maintaining the correct profile of the trim strip, the window-door system operates smoothly, and the risk of premature wear of the window lifting mechanism is reduced.

Construction, color, and fitment

The presented trim strip is finished in black, which allows for a cohesive visual integration with factory window frames and other door trim elements in the BMW F45 series. The construction has been prepared specifically for installation on the rear left side, which means it matches the door shape and the correct layout of mounting points.

A properly selected working profile of the trim strip ensures even pressure against the window surface, which translates into stable water wiping and reduced streaking. The use of original geometry minimizes the need for additional adjustments after installation.

Condition, origin, and technical parameters

The component comes from the BMW range and belongs to the Window seals and trim strips group, which guarantees compatibility with factory design solutions used in F45 models. The product is in used condition, allowing for an economical replacement while maintaining proper fitment to the bodywork.

The trim strip is designed to work in the rear part of the body on the left side, taking into account the specific shape of the door and the window guidance in this area. As a result, installation is predictable, and once properly seated, the component maintains stability during operation.

Benefits of using the weatherstrip

Using the correct weatherstrip in a BMW F45 brings a number of practical operational benefits:

• better protection of the door interior against water and contaminants,
• reduced risk of corrosion for metal components inside the door,
• more stable window operation at higher speeds,
• more predictable operation of the window lifting mechanism,
• maintaining the aesthetic appearance of the window edge and door frame.

For users who want to restore the correct operation of the window after body repairs or door replacement, using the appropriate weatherstrip is one of the key stages in completing the side body equipment.
