Technical Information
- Manufacturer: Stellantis / Peugeot
- Model: Peugeot 307 (Not Suitable For Peugeot 307 CC Convertible)
- Product Codes: 9637130580, 9221N3
- Other Numbers: 9221N3 | 9637130580
Installation Recommendations
- Always disconnect the vehicle battery before starting work to avoid short circuits and to protect vehicle electronics.
- Remove the interior door trim carefully (remove visible screws, pry out clips with a trim tool) to access the regulator and motor.
- Lower the window glass to a position where you can unbolt the glass from the regulator, then support or tape the glass to prevent movement.
- Disconnect the electrical connector from the motor and remove the mounting bolts holding the motor to the regulator.
- Install the new motor in reverse order: secure mounting bolts, reconnect electrical connector, temporarily reconnect battery to test full up/down travel before reassembling the door trim.
- Check and lubricate regulator tracks and guide points with suitable grease to ensure smooth operation and reduce wear.
- Test the complete function several times (including mirror folding if applicable) and ensure correct window alignment before final assembly.
Why This Part Fails Most Often
- Wear Of Internal Components: Brushes, commutator, and reduction gears wear over time with frequent use, reducing motor torque or causing failure.
- Water Ingress And Corrosion: Moisture entering the door can corrode electrical contacts or gear assemblies, especially on older seals or after door damage.
- Mechanical Stress: Jammed glass, bent regulator rails, or frayed cables place extra load on the motor and accelerate wear or strip gears.
- Contaminants And Dirt: Debris in the regulator tracks increases friction and load on the motor.
Notes For Mechanics And DIYers
This motor is a direct-fit solution for a wide range of Peugeot 307 applications (check the product codes 9637130580 and 9221N3 when searching). When replacing the motor, verify the regulator condition; often a noisy or sticking regulator will shorten the life of a new motor if underlying mechanical faults are not addressed. Proper lubrication and ensuring the window runs freely will extend service life.
