Construction and fitment for Mercedes W245

The window lifter is designed as a component mounted inside the door, within the window guide zone. Its geometry and mounting points are adapted to the Mercedes W245 door structure, which facilitates installation and allows for maintaining the correct position of the window relative to the seals and the door frame.

The product belongs to the Window regulators and motors category, meaning it is intended for use with the electric window control system, providing the necessary force and stability of window movement throughout the full range of operation.

Benefits of using a pre-owned window lifter

Choosing a pre-owned window lifter for a Mercedes W245 is a solution that helps reduce repair costs while maintaining the original design of the component.

The main advantages of this solution include:

• maintaining factory fitment to the door and window,
• compatibility with the original window lifter motor,
• the ability to restore proper mechanism operation without interfering with the door structure.
