This high-quality replacement right front window motor is designed for Peugeot 307 CC models and is commonly sought under OE numbers 9660037780 and 9222CL. Engineered to operate the passenger-side window and to integrate the mirror folding and door-handle-linked functions, it is a practical solution for workshops and experienced DIYers looking to restore reliable window operation. The motor is suited for direct-fit installation on compatible door assemblies and provides the torque and control needed for smooth up/down movement under normal conditions.

Technical Information

• Manufacturer: Stellantis (Citroën / Peugeot)
• Model: Peugeot 307 CC (from 2005) — Right Front / Passenger Door
• Product Codes: 9660037780, 9222CL
• Additional Numbers: NFP

Installation Recommendations

• Always disconnect the battery before starting work to avoid short circuits and accidental activation.
• Remove the door trim panel and protective vapor barrier carefully to access the regulator and motor. Keep fasteners and clips organized for reassembly.
• Support the window glass in the fully up position (use tape or a suitable support) before detaching the motor or regulator to prevent glass drop or damage.
• Disconnect the electrical connector and unbolt the motor from the regulator. Inspect the regulator, guide rails, and mounting points for wear or damage and replace if necessary.
• After installation, check window travel for smooth operation, proper alignment, and absence of binding. Re-lubricate guide rails with appropriate greases if needed.
• Follow manufacturer torque values and mounting procedures where specified to avoid deformation of components.

Why This Part Fails

• Water Ingress And Corrosion: Moisture entering the door can corrode gears and electrical contacts, causing intermittent or permanent failure.
• Mechanical Wear: Gears, splines, and plastic worm gears eventually wear out after years of use, leading to slipping or loss of drive.
• Regulator Problems: Frayed cables or worn regulator tracks increase load on the motor, causing overheating or premature burnout.
• Electrical Issues: Connector corrosion, broken wires, or failed switches can interrupt power supply to the motor.
• Overload From Binding Window: Misaligned glass or debris in the track forces the motor to work harder, shortening its service life.
• Typical Service Life: Varies with use and environment; many units remain functional for 8–15 years, but heavy use or poor sealing can reduce longevity.

How To Replace

1. Disconnect the negative battery terminal.
2. Remove inner door trim and detach the plastic vapor barrier carefully.
3. Manually move the window to a position that allows access to the motor fasteners and secure the glass in place.
4. Disconnect the motor electrical connector and unbolt the motor from the regulator assembly.
5. Remove the motor (and regulator if required) and fit the new unit in the reverse order. Ensure correct engagement of splines/gears with the regulator.
6. Reconnect the battery, test window operation through full travel, and check mirror folding and handle-linked functions for correct behavior.
7. Reassemble the vapor barrier and trim panel, ensuring all clips and fasteners are secured.
