Used electric window regulator for the right front (passenger) door, suitable for Citroën C4 five‑door models of the first generation. This replacement mechanism restores smooth and reliable operation of the window with original-fit mounting points and electrical connector. The unit is often searched by OE and aftermarket numbers (e.g. 9657133580, 1629054680, 9222V0), so listing part codes increases findability for workshops and DIY customers.

Technical Information

• Manufacturer: Stellantis / Citroën
• Model: Citroën C4 (5‑door), First Series
• Product Codes: 9657133580
• Other Numbers: 1629054680, 9222V0

Function And Application

The regulator assembly converts the electric motor rotation into vertical movement of the window glass. It includes the guide, cable/sliders and mounting brackets that secure the glass and allow precise travel. This part is designed for the right front (passenger) door and is compatible with first‑generation Citroën C4 five‑door body styles. Ideal for workshops and experienced DIY mechanics who replace door internals.

Typical Failure Modes And Lifespan

Window regulators commonly fail due to worn plastic sliders, frayed or snapped cables, motor wear or electric connector corrosion. Water ingress and salt exposure accelerate wear in lower door cavities. Under normal use many units last several years, but units on high‑use vehicles or cars exposed to moisture often need replacement after roughly 8–15 years or earlier if mechanical damage occurs.

Replacement Procedure (Summary)

1. Prepare Tools: panel trim tools, Torx/Sockets, screwdriver, rivet/drill if rivets are used, gloves and protective eyewear.
2. Safety: Disconnect the battery negative terminal before starting to avoid short circuits and accidental motor activation.
3. Remove Door Trim: Carefully pry off trim clips, detach door handle and electrical connectors, and remove screws securing the panel.
4. Remove Moisture Shield: Peel back the plastic vapor barrier to access inner door components.
5. Support Glass: Manually position and secure the window glass (tape to the top of the door frame or use an assistant) to prevent it from falling when the regulator is removed.
6. Disconnect Motor And Unbolt Regulator: Unplug the motor connector, remove regulator mounting bolts and glass clamps, then extract the assembly.
7. Install New Unit: Fit the replacement regulator, loosely install bolts, reconnect motor and test window operation before final torque.
8. Reassemble: Refit vapor barrier, door trim and all electrical connectors. Reconnect battery and perform final functional check.

Installation Recommendations

• Always Disconnect Battery: For electrical safety, disconnect the negative battery terminal before working on door electrics.
• Test Before Final Reassembly: After installing the regulator and reconnecting the motor, operate the window through full travel to ensure smooth movement and correct alignment before tightening all fasteners and refitting trim.
• Inspect Glass Run Channels And Seals: Replace or lubricate worn rubber guides to prevent premature wear of the new regulator.
• Use Correct Fasteners: Replace any damaged clips, screws or rivets to restore original mounting strength and NVH performance.
• Protect Electrical Connectors: Clean and apply dielectric grease if connectors show corrosion to improve longevity.

Why This Part Commonly Fails

The most frequent causes of failure are mechanical wear of plastic sliders or cable guides, motor burnout from heavy use or short circuits, and corrosion from moisture ingress. Obstructions in the window track or misaligned glass increase load on the regulator and accelerate failure. Regular inspection and keeping door drains clear reduce risk.

Compatibility Note

This regulator is intended for Citroën C4 five‑door models of the first generation. Customers often search by OE numbers 9657133580, 1629054680 or reference 9222V0; use these codes when checking fitment in parts databases or workshop manuals.
