Fitment
Intended for Citroën C4 First Series vehicles as the right front (passenger) door window motor. Fits units that use OE numbers listed above. Always confirm part numbers printed on the old unit before installation.
Installation Recommendation
Recommended for fitment by trained technicians or experienced DIYers. Typical replacement steps:
- Disconnect the vehicle battery before starting work to avoid short circuits and to reset comfort electronics where applicable.
- Remove the door trim and moisture barrier carefully, keeping clips and screws organized.
- Lower the window glass (if possible) to access the regulator mounting points, or support the glass securely if it cannot be moved.
- Unplug the electrical connector to the motor and remove the securing bolts that hold the motor to the regulator/door.
- Remove the motor from the regulator assembly. Transfer any required parts (spacers, washers) to the new motor if needed.
- Install the new motor, tighten fasteners to the manufacturer’s torque where available, reconnect the electrical connector and test window operation before reassembling the door trim.
- Reinstall the moisture barrier and door trim. Reconnect the battery and perform a few full up/down cycles to confirm correct operation and alignment.
When reinstalling, check gear mesh and avoid forcing the window if resistance is felt. If the regulator mechanism shows excessive play or damaged plastic gears, replace the regulator assembly together with the motor.
Why This Part Fails Most Often
Common failure causes include:
- Mechanical Wear: Worn brushes or commutator wear inside the motor and degraded gear teeth (often plastic) in the regulator.
- Water Ingress And Corrosion: Moisture entering the door can corrode electrical contacts or drive gears.
- Overload And Jamming: Misaligned glass, debris in the window channel, or a seized regulator places extra load on the motor and can strip gears or burn the motor.
- Electrical Issues: Corroded connectors, poor ground, or intermittent switch faults can cause sporadic operation that stresses the motor.
Practical Tips
- Inspect the regulator and guides before installing the motor—replacing the motor alone may not solve the problem if the regulator is damaged.
- Clean and lubricate window channels and pivot points to reduce load on the motor and extend service life.
- Use correct tools and follow manufacturer procedures for door trim removal to avoid breaking clips or damaging the moisture barrier.
Ordering
