Purpose and function of the mechanism

The presented mechanism is intended for installation in the rear right part of the body, where it is responsible for precise, manual lifting and lowering of the window. The design, adapted to the specific Skoda model, allows for proper window guidance in the tracks, minimizing the risk of jamming, misalignment, or excessive play during handle operation.

This element is particularly important in vehicles that have retained classic manual controls – it ensures repeatable window movement, proper torque transfer from the handle mechanism to the guides, and stability of the glass pane in various positions.

Compatibility with the vehicle system

The mechanism has been designed to work with a manual window control system, which means full integration with the factory handle and other door components. Its placement in the rear right part of the body allows for direct replacement of a worn or damaged element without the need for modifying the door structure.

This solution is beneficial both for standard repairs and for restoring full window functionality after a collision or bodywork intervention. Using an original mechanism helps maintain consistent operation of all windows in the vehicle and reduces the risk of improper upholstery fitment.

Technical and operational characteristics

The manual window lifter mechanism has been developed to work with the chassis and drivetrain of a vehicle equipped with a manual transmission. This ensures compliance with the factory configuration of the car, which facilitates diagnostics and subsequent maintenance.

The design parameters have been selected to ensure adequate rigidity and durability during repeated window opening and closing cycles. The mechanism works with doors designed for a specific rim width in the factory configuration, which is important for maintaining the vehicle's original design assumptions.

Condition, installation, and practical application

The offered item is in used condition, which allows for economical repair while maintaining the manufacturer's original specifications. This solution is particularly advantageous for comprehensive service work, where both factory compliance and rational operating costs are important.

The mechanism will prove useful for:

• replacing a damaged window lifting system after a mechanical failure,
• post-accident repairs of the rear body section,
• restoring full functionality of the rear passenger door after body and paint work.

Using an original solution from the Window regulators and motors group limits the risk of fitment issues and ensures predictable window behavior throughout its entire range of operation.
