Purpose and vehicle placement

The presented motor is dedicated for installation in the rear left door area of the Ford B-Max Mk1. It works directly with the window regulator mechanism, responsible for the smooth movement of the glass in the guides. Thanks to its precise fit to the door structure, it maintains the correct operating geometry, which reduces the risk of jamming and uneven closing.

The placement on the vehicle defined as rear – left side allows for unambiguous identification of the correct component when planning repairs or replacement. This is particularly important when working with electric window regulators, where differences between the left and right sides and the front and rear of the vehicle are crucial for proper installation.

Technical and functional characteristics

The window regulator motor in the Ford B-Max Mk1 works with the door's electrical system, transmitting torque to the lifting mechanism. The appropriately selected gear ratio and drive design ensure:

• controlled speed of raising and lowering the window,
• stable operation throughout the full range of motion,
• reduction of mechanical loads in the guide system.

Thanks to the use of an original solution from the Window Regulators and Motors group, compatibility with the factory window control and other door equipment elements, such as the wiring harness or control panel, is maintained.

Component condition and benefits of use

The offered motor comes from dismantling and is a used part, which allows for combining reasonable repair costs with maintaining the factory design. Choosing such a solution is particularly beneficial when you want to:

• maintain the original window operating characteristics,
• match the existing regulator mechanism,
• reduce service costs while maintaining appropriate quality.

Using the correct motor in the rear left door allows for restoring the vehicle's comfort – passengers gain a smoothly operating window, and the electrical system is not burdened by a malfunctioning drive.

Selection, identification, and vehicle integration

To correctly select the window regulator motor for the Ford B-Max Mk1, it is crucial to pay attention to the mounting side and the model generation. The component intended for the rear – left side should not be used interchangeably with other positions in the vehicle, as structural differences may prevent proper installation or disrupt the mechanism's operation.

The motor is designed to work with the factory window control system, so after proper connection to the electrical installation, it integrates with existing vehicle functions, such as control from the driver's panel or the local button in the door. This solution allows for maintaining the consistency of the entire electric window system.
