Purpose and function in the Ford B-Max

The presented window regulator motor is dedicated to the rear left section of the Ford B-Max body, where it is responsible for driving the window mechanism in the sliding door. As a component of the window control system, it works with the vehicle's electrical installation and factory switches, allowing for convenient opening and closing of the window from inside the cabin.

By using an original Ford solution, the correct geometry of the mechanism's operation, the appropriate window movement speed, and the stability of the glass in the guides are maintained. This is particularly important in sliding doors, where the system must operate in varying positions relative to the body.

Construction and performance parameters

The rear left window regulator motor in the Ford B-Max is an integrated electric drive designed to work with the factory window regulator. The design is intended for installation in the rear part of the vehicle on the left side, taking into account the specific layout of guides and mounts in the sliding door.

The original construction ensures:

• torque appropriately matched to the weight of the window and the resistance of the guides,
• stable operation throughout the full range of window movement,
• compatibility with factory mounting points in the door,
• proper cooperation with the electrical installation and comfort control system.

Benefits of using an original motor

Using an original window regulator motor in the Ford B-Max allows for maintaining the consistency of the entire window system. Factory fitment minimizes the risk of incorrect installation, excessive play, or overloading of the mechanism. In practice, this means less strain on other components of the regulator and reduced noise during window operation.

The used OEM component is also a reasonable compromise between repair cost and quality – you retain the manufacturer's original specification while optimizing your service budget. This solution is particularly beneficial for complex sliding door repairs, where both durability and operational economy are important.

Condition, verification, and installation

The motor comes from dismantling and is offered as a used part, which allows for an economical repair of the window system in the Ford B-Max. Before being offered for sale, such components are standardly verified for correct drive operation and response to control signals, which reduces the risk of problems after installation.

When replacing, it is recommended to:

• check the mechanical condition of the regulator guides and cables,
• verify the electrical wiring in the sliding door,
• check the correct operation of the window in the full range after installation.
