Purpose and function of the window lifter

The presented window lifter is dedicated to the front right door in Mercedes A and B Class models of the W169/W245 generation. Its task is stable raising and lowering of the window within the guides, while maintaining proper operating geometry and appropriate clamping force. As a result, the window moves smoothly, without jamming or excessive play, which reduces the risk of damage to seals and excessive noise while driving.

The vehicle placement defined as front – right side allows for unambiguous identification of the component during part selection and planning of passenger door repairs.

Construction and mounting parameters

The window lifter belongs to the Window Regulators & Motors group, which means it works with the door window control system, transmitting drive to the window via an appropriate guide mechanism. The design is prepared for installation in factory mounting points in the door, which facilitates service and shortens replacement time.

Key mounting features of this component include:

• dedicated fitment for the front right door in Mercedes A/B W169/W245,
• designed for compatibility with the factory window control system,
• geometry consistent with the original door construction, which facilitates correct window alignment.

Condition and service application

The item is offered in used condition, which allows for economical repair of the window lifting system while maintaining compliance with factory specifications. This type of part is suitable both for typical replacement of a worn or damaged mechanism and for comprehensive door renovation after a collision or bodywork intervention.

The selection of a window lifter for a specific vehicle should always be verified based on car data as well as the OEM number and interchangeable numbers visible in the technical specification, which minimizes the risk of incorrect fitment.

Benefits of using an original window lifter

Using a window lifter dedicated to a specific generation of Mercedes A and B Class ensures:

• proper cooperation with the factory window controls and the vehicle's electrical installation,
• appropriate window guidance in the door, which reduces stress and accelerated wear of sealing elements,
• consistency with the door construction, which facilitates installation and subsequent adjustments.

For workshops and individual users, this means faster repair completion and a lower risk of needing to remove the door upholstery again for installation adjustments.

Part selection and technical support

When selecting a window lifter for a specific Mercedes, it is worth using the OEM markings and reference numbers provided in the specification section, as well as vehicle data (model, year, body version). In case of doubt, comparing the construction with the currently installed component after removing the door upholstery may be helpful.
