Description
Left front window regulator motor for Peugeot 307. Without folding mirror function for the vehicle. Not suitable for CC convertible.
Replacement left front window motor designed for Peugeot 307 vehicles. This unit is commonly sought under part numbers 9634457580 and 9221N5 and is intended for mechanics and experienced DIYers who need a reliable repair part for a non-CC (non-convertible) 307. The motor drives the window regulator mechanism to raise and lower the glass and is supplied as a direct-fit component for compatible regulator assemblies.
This motor is a mechanical-electrical assembly that converts electrical input from the window switch into rotational force transmitted to the regulator gears or cable drum. Typical symptoms indicating motor failure include slow or intermittent window movement, grinding or clicking noises inside the door, the window failing to move or stopping mid-travel, and increased current draw at the switch. The unit does not provide any folding-mirror functionality and therefore is not suitable for vehicles where mirror folding function is integrated with the motor/regulator.
Technical Information

- Model: Peugeot 307 (Left Front)
- Product Codes: 9634457580, 9221N5
- Additional Numbers: NFP (as indicated in supplied data)
Installation Recommendations
Suitable for professional installation or experienced DIY mechanics. Typical replacement procedure:
- Disconnect the vehicle battery before beginning work to avoid short circuits and accidental window movement.
- Remove inner door trim and any moisture barriers to access the regulator and motor.
- Support the window glass in the fully up position (use tape or a helper) before detaching the motor from the regulator.
- Disconnect the electrical connector and remove the motor mounting bolts. Depending on design, you may need to separate the motor from the regulator assembly or replace the entire regulator with motor.
- Fit the replacement motor, secure mounting bolts to manufacturer torque where available, reconnect the electrical connector and test the window operation before reassembling the door.
- Reinstall moisture barrier and door trim, reconnect the battery and perform final function checks.
Why The Part Most Often Fails
- Water Ingress And Corrosion: Moisture inside the door can corrode brushes, commutator or electrical contacts.
- Mechanical Wear: Worn brushes, bearings or stripped plastic/nylon gears reduce torque or cause grinding.
- Regulator Strain: Jammed or bent regulator components (cables, tracks) increase load on the motor and accelerate failure.
- Contaminants And Debris: Dirt and grit in the regulator mechanism increase friction and wear.
- Electrical Issues Upstream: Faulty switch, connector corrosion or wiring problems can mimic motor failure but also damage the motor over time.
Compatibility Notes
Intended For Peugeot 307 Left Front Application. Does Not Include Folding Mirror Functionality. Not Suitable For CC Convertible Models.
Advice For Buyers
Searches Often Use The Part Numbers 9634457580 Or 9221N5—Include These References When Looking Up Fits. If Replacing The Motor, Inspect The Regulator Mechanism And Window Guides For Wear; Replacing Only The Motor When The Regulator Is Damaged May Result In Premature Failure.
