Application And Compatibility
Direct replacement for the left front (driver) door of Citroën C5 second generation models manufactured between 2005 and 2007. Intended for vehicles that use the listed part numbers. Fits vehicles with combined power window motor and electric mirror folding control.
Function And Typical Symptoms
The motor drives the window regulator mechanism to raise and lower the left front window and integrates the control for the electric folding mirror. Common symptoms of a failing unit include slow or intermittent window movement, complete loss of window function at the driver side, unusual grinding or buzzing noises during operation, and failure of the mirror folding feature when the mirror command is activated.
Most Common Failure Causes
- Mechanical wear of internal gears and regulator linkages caused by long service life and repeated use.
- Water ingress and corrosion inside the motor or connector leading to electrical faults or seized components.
- Worn motor brushes or armature deterioration resulting in reduced torque and intermittent operation.
- Damaged wiring, poor terminal contacts, or faulty switches causing loss of power to the motor.
- Overload from a jammed window or bent regulator that increases stress on the motor and accelerates failure.
Installation Recommendations
- Tools Required: Trim removal tools, Torx and Phillips screwdrivers, socket set, pliers, and a non-marring support for the glass.
- Safety: Disconnect the negative battery terminal before starting work to avoid short circuits or accidental window movement.
- Procedure Overview: Remove interior door trim and moisture barrier carefully; support the glass in its position; detach the window from the regulator; unbolt and disconnect the motor electrical connector; install replacement motor, reconnect wiring and test operation before reassembling the door.
- Testing: Cycle the window several times and verify mirror folding function after installation to ensure correct operation and that the regulator moves freely.
- Tips: Keep fasteners and clips organized, replace any damaged vapor barrier to prevent future moisture ingress, and lubricate regulator pivot points with a suitable grease for smooth operation.
Why Replace This Part
Replacing the motor resolves loss of window function and restores convenience and safety for the driver. A properly functioning motor prevents water ingress into the door cavity caused by gaps when the window cannot fully close and avoids further damage to the regulator and associated electrical components.
For Whom This Part Is Intended
Designed for professional mechanics and competent DIY enthusiasts familiar with door trim removal and basic electrical disconnection. Suitable when the listed product codes match the vehicle’s requirements.
