Technical information
- Manufacturer: Stellantis (Peugeot/Citroën)
- Model: Peugeot 307 (Phase 1 and Phase 2) – Right Rear / Passenger Side Window Regulator
- Product codes: 9224A4
- Other numbers: NFP
Features and Benefits
- Complete regulator mechanism with electric motor ready for direct replacement.
- Restores reliable window travel and reduces noise compared with worn originals.
- Designed to fit the factory mounting points for straightforward installation.
- Saves diagnostic time for workshops by targeting a common failure item on Peugeot 307 rear doors.
Installation Recommendations
- Disconnect the battery before starting work to avoid short circuits and accidental window movement.
- Remove the inner door trim carefully (retain fasteners and clips). Detach any vapor barriers without tearing where possible.
- Support the window glass in its up position (tape or suction support) before removing the regulator retaining bolts.
- Disconnect the electrical connector to the motor, then remove the regulator assembly from the door.
- Fit the new regulator: align mounting points, loosely install bolts, reconnect the motor and test window travel through full cycles to set alignment, then tighten fasteners to manufacturer torque where available.
- Lubricate guide rails and moving joints with an appropriate dry or silicone-based lubricant to prolong service life.
- Reinstall the door trim and test the window operation several times to confirm smooth and consistent movement before handing the vehicle back.
Why This Part Fails
Window regulators on Peugeot 307 commonly fail due to a combination of mechanical wear and environmental factors. Typical causes include worn motor brushes, corrosion from water ingress, frayed cables or broken plastic sliders, and seized guides caused by dirt or lack of lubrication. Symptoms include slow or jerky window movement, grinding or rattling noises, intermittent operation, the window falling out of alignment, or complete loss of movement.
Practical Tips for Mechanics
- Inspect the door wiring harness and connector pins for corrosion or damage before fitting the new regulator.
- If the glass is off-track or mounting clips are broken, replace those components during the same repair to avoid repeat visits.
- Run the window through several cycles after installation to ensure the regulator and glass seat correctly and that the motor draws normal current (excessive current may indicate binding).
- Keep the part number 9224A4 handy when ordering or searching; many customers look up this reference directly.
Typical Application
Direct replacement for the right rear passenger side electric window regulator on Peugeot 307 models (Phase 1 and Phase 2). Suitable for professional installation in service garages and for experienced DIY enthusiasts familiar with door trim removal and electrical connectors.
Replacement Interval
There is no fixed interval; replace the regulator when symptoms appear or during door restoration. Regular inspection and lubrication of the sliding mechanisms can extend service life.
