Application And Function
The unit is an electric window lift motor that drives the regulator mechanism, converting electrical input into the rotational motion that moves the window glass up and down. It is fitted to the right front (passenger) door of the Peugeot 407. Some versions include an electrical folding-related function as noted in the original description; ensure the wiring connectors and mechanical interfaces match the vehicle when fitting.
How To Replace
- Disconnect The Battery: Always disconnect the negative battery terminal before starting work to avoid short circuits and accidental operation.
- Remove Door Trim: Carefully remove interior door panel and trim clips. Keep screws and clips organised.
- Remove Water Shield: Peel back the vapour/water barrier to access the regulator and motor.
- Support The Glass: Secure the window glass in the closed or raised position with tape or a support to prevent it falling when the regulator is disconnected.
- Disconnect Wiring: Unplug the motor electrical connector.
- Unbolt Motor From Regulator: Remove bolts fixing the motor to the regulator mechanism. If the motor is integrated with the regulator, remove the entire assembly as required.
- Install New Motor: Position the new motor, tighten mounting bolts, reconnect the wiring and test the window operation before reassembling the door.
- Reassemble Door: Replace the water shield and door trim. Reconnect the battery and test final operation.
Installation Recommendations
- Use Correct Tools: A set of trim tools and the correct sockets will prevent damage to clips and panels.
- Test Before Reassembly: Verify full window travel and check for binding or unusual noises before refitting the door card.
- Protect The Glass: Secure the glass during motor removal to avoid breakage or misalignment.
- Check Drainage And Seals: Clear door drain holes and ensure the water shield is reseated correctly to prevent future water ingress.
Why The Part Fails
Window motors commonly fail due to a combination of mechanical wear and environmental factors. Typical causes include:
- Worn Brushes Or Commutator In The Motor Leading To Loss Of Power.
- Gear Wear Or Stripped Teeth In The Motor Or Regulator Assembly.
- Water Ingress And Corrosion Causing Electrical Faults Or Seizure.
- Regulator Cable Fraying Or Detachment Resulting In Increased Motor Load.
- Excessive Friction From Worn Guides Or Misaligned Glass Causing Overload.
Maintenance Tips
- Keep Window Tracks And Guides Clean And Lightly Lubricated With Appropriate Grease.
- Avoid Forcing A Jammed Window; Inspect And Free Any Obstructions Promptly.
- Ensure Door Drain Channels Are Clear To Reduce Water Exposure To The Motor.
Compatibility And Identification
Search By Part Number For Fast Identification: Use the product codes 1137328127 and 9222Y9 when checking compatibility lists or parts databases to ensure you order the correct right front window motor for the Peugeot 407.
Final Note
This description is intended for professional mechanics and experienced DIYers. If the regulator shows visible mechanical damage (bent arms, frayed cables) it is recommended to replace the entire regulator assembly together with the motor to restore correct and long-lasting operation.
