Designed for professional workshops and experienced DIY mechanics who demand reliable movement, quiet operation and easy fitting. Commonly searched under part numbers 9222P5 and 1629054880, this regulator restores smooth window travel and eliminates rattles, stuck glass or slow operation caused by worn cables, guides or motor wear.
Technical Information
- Manufacturer: Stellantis / Citroën
- Model: Citroën C5 (2001–2007) – Right Front (Passenger) Door
- Product Codes: 9222P5
- Additional Numbers: 1629054880, NFP
Fitment And Application
Fits Citroën C5 first generation models produced between 2001 and 2007 for the right front (passenger) door. This unit replaces the electric window regulator assembly used to raise and lower the glass.
Function And Typical Failure Modes
The window regulator assembly guides and supports the door glass and converts the electric motor’s rotation into vertical movement. Typical causes of failure include:
- Worn or frayed steel cables and plastic guides causing seized or uneven movement.
- Degraded or broken plastic sliders/clips that allow the glass to detach or bind.
- Corrosion or dirt ingress in the regulator tracks leading to increased friction.
- Motor wear (brushes or gearbox) resulting in slow or non-operational window movement.
- Water ingress from damaged door seals accelerating wear of the mechanism.
Replacement Procedure
Basic steps for replacing the front passenger window regulator. Intended for trained technicians or experienced DIYers:
- Disconnect the negative battery terminal before starting work to avoid short circuits and accidental motor activation.
- Remove the door trim panel and any vapor barrier carefully to access the regulator and motor.
- Secure the glass in the fully up position (use suction cups or tape) or remove the glass if required by the vehicle design.
- Unplug the regulator motor electrical connector and remove the mounting bolts securing the motor and regulator to the door shell.
- Carefully extract the old regulator assembly from the door and transfer any reusable components if applicable.
- Install the new regulator, align the glass carriers, tighten fasteners to manufacturer recommendations, and reconnect the wiring.
- Test the window operation through several full cycles to verify smooth travel and correct alignment before refitting the door trim.
Installation Recommendations
- Always disconnect the battery prior to removal and follow vehicle manufacturer procedures.
- Lubricate guide rails and moving contact points with a suitable high-quality white lithium or silicone grease to reduce wear and noise.
- Check door seals and drainage holes for blockage; clear any debris to prevent premature corrosion and water ingress.
- Verify motor operation and regulator alignment before completing reassembly. Cycle the window several times to seat components correctly.
- Use correct torque values for fasteners as specified by the manufacturer to avoid deformation or loosening.
Why This Part Fails Most Often
Window regulators typically fail due to mechanical wear and environmental exposure. Frequent use, abrasive dirt or water entering the door, and broken plastic sliders or cable fraying are the most common reasons. Addressing worn seals and ensuring regular lubrication can significantly extend service life.
This replacement part is ideal for workshops and competent home mechanics who need a direct-fit solution that is straightforward to install and restores reliable window function.
