Vehicle Application and Placement

The regulator is designed for installation in the area of the rear left window in the BMW F23 Cabrio. The construction, tailored to the specific body type, ensures proper window guidance in the tracks and compatibility with the factory window control mechanism.

Precise placement on the vehicle reduces the risk of glass stress, minimizes operating noise, and maintains window sealing and proper contact with the weatherstrips.

Technical and Functional Characteristics

This component belongs to the Window Regulators and Motors group, meaning it is responsible for the mechanical movement of the window in response to a signal from the control button. The regulator's design is adapted to the specifics of a convertible door, where precise window positioning relative to the roof and seals is crucial.

Key functional features include:

• dedicated fitment for the rear left side of the F23 Cabrio body,
• compatibility with the factory BMW window control system,
• engineered geometry of arms and guides, ensuring stable window movement.

Benefits of Using an Original BMW Regulator

Using an original body window regulator in the BMW F23 Cabrio allows for the preservation of the window mechanism's original operating parameters. Proper fitment with the door and window reduces the risk of jamming, uneven lifting, and excessive strain on the control motor.

In practice, this translates to:

• stable, repeatable window movement without jerking,
• reduced wear on cooperating window system components,
• maintenance of acoustic comfort within the vehicle's interior.

Product Condition and Service Application

The regulator is offered as a used original BMW part, providing a sensible compromise between repair cost and maintaining factory fitment quality. This type of part is suitable for both routine replacement of a worn mechanism and for post-accident repairs where restoring proper window function in the rear door is necessary.

When selecting components for the window system, it is advisable to use OEM and cross-reference numbers for identification.
