Description
Left front window motor for Peugeot 307 CC from 2005. With mirror folding function linked to the vehicle and handle control. Tested, fully functional. Driver’s door.
Product Overview
This replacement left front window motor is intended for the drivers door of the Peugeot 307 CC (convertible). It operates the front left window and includes the vehicle-linked mirror folding function and handle control interface. The unit is a direct-fit solution for workshops and DIY mechanics who search by OE numbers 9660037880, 9681588980 or 9221CN.
Technical Information
- Manufacturer: Stellantis (Peugeot/Citroën)
- Model: Peugeot 307 CC (from 2005)
- Product Codes: 9660037880, 9681588980, 9221CN
- Other Numbers: NFP (where indicated by vendor data)
- Location: Left Front (Driver’s Door)
Function And Typical Faults
The motor drives the window regulator to raise and lower the glass. It also integrates with the mirror folding function and the door handle control circuitry. Common reasons for failure include mechanical wear (worn gears or stripped teeth), carbon brush wear inside the motor, water ingress and corrosion in the door cavity, regulator binding or broken regulator cables, and electrical faults such as damaged wiring, corroded connectors or a failed switch.
Replacement Procedure (Summary)
- Disconnect Battery: As a safety precaution, disconnect the negative battery terminal before starting work.
- Remove Door Trim: Carefully remove the interior door panel and any trim clips to access the door internals.
- Take Off Moisture Barrier: Peel back the water shield to expose the regulator and motor assembly.
- Unplug Electrical Connector: Disconnect the motor wiring connector and any linked sensors or switches.
- Unbolt Motor From Regulator: Remove the fasteners securing the motor to the regulator and detach the motor.
- Install New Unit: Fit the replacement motor, secure bolts, reconnect the electrical plug and test the window and mirror folding function before reassembling the door.
- Reassemble Door: Refit the moisture barrier and door trim. Verify operation of the window, mirror fold and handle functions.
Installation Recommendations
- Test Before Final Assembly: Always verify full function (up/down window travel, automatic limits and mirror folding) before refitting the door panel.
- Inspect Regulator: Check the regulator tracks, cables and guide rollers for wear; replace the regulator if damaged to avoid premature motor overload.
- Clean And Protect Connectors: Clean electrical connectors and apply dielectric grease to reduce corrosion risk in the door environment.
- Lubricate Moving Parts: Use suitable window track grease on guide channels to lower friction and extend motor life.
- Check Door Drainage: Ensure door drains are clear to minimise water ingress that can corrode the motor and connectors.
Why This Part Fails Most Often
- Mechanical Wear: Gears and internal drive components wear out over years of operation.
- Brush Wear: Carbon brushes inside the motor degrade and reduce electrical contact.
- Water Ingress And Corrosion: Moisture in the door causes corrosion of contacts and motor internals.
- Regulator Binding: A seized or stiff regulator increases load on the motor and leads to premature failure.
- Electrical Issues: Damaged wiring, corroded connectors or faulty switches can mimic motor failure.
Notes For Buyers
This item is commonly searched by OE numbers 9660037880, 9681588980 and 9221CN. Suitable primarily for Peugeot 307 CC left front applications from 2005 onward. Professionals and competent DIY mechanics will be able to replace this unit using standard tools; check regulator condition during fitting to ensure long-term reliability.
