Purpose and function in the vehicle

The presented motor belongs to the Wiper motors and linkages group and is responsible for driving the rear wiper in the Ford Focus Mk3. Located in the rear of the vehicle, it works with the wiper arm and blade, generating the appropriate torque for smooth movement across the glass. A properly functioning rear wiper drive is crucial for maintaining clear visibility in the rearview mirror during rain, snow, or while driving on dirty roads.

The element has been designed as a component dedicated to a specific Ford platform, which translates into:

• proper fitment with body mounts,
• compatibility with the vehicle’s electrical system,
• stable cooperation with the factory wiper control system.

Construction and technical fitment

The rear wiper motor in the Ford Focus Mk3 is an electrical assembly adapted for operation in the rear part of the body, where it is exposed to variable temperatures, moisture, and vibrations. The housing and mounting method have been developed to provide adequate protection for the mechanism while allowing for service disassembly if necessary. The applied design solutions allow for:

• stable power transmission to the wiper axis,
• maintaining a repeatable range of arm movement,
• reduction of noise and vibration during operation.

Thanks to the preservation of factory mounting parameters, the motor can be used as a direct replacement for a damaged element, without the need for installation modifications or mounting alterations.

Condition, verification, and service application

The offered component is used, which in practice means it comes from disassembly but has been verified for suitability for further use. This type of part is a good choice in situations where:

• the original rear wiper drive has suffered mechanical or electrical damage,
• there are problems with the arm stopping in an incorrect position,
• the motor operates irregularly or has completely stopped responding to controls.

Using an original, used element allows for maintaining performance characteristics close to factory standards while reducing repair costs compared to new components.

Benefits of using a dedicated rear wiper motor

Replacing a faulty rear wiper drive with the correct model intended for the Ford Focus Mk3 brings a number of practical benefits:

• Restoration of full rear wiper functionality – improved visibility in rain, snow, and slush.
• Compatibility with the vehicle’s system – no need for electrical harness or mounting modifications.
• Stable system operation – correct range of arm movement and predictable performance in wiper operating modes.
• Solution consistent with Ford’s design – maintaining consistency with other wiper system components.

For workshops and individual users, this means a simpler service process and a lower risk of compatibility issues.
