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

1. Disconnect The Battery: Always disconnect the negative battery terminal before starting work to avoid short circuits and accidental operation.
2. Remove Door Trim: Carefully remove interior door panel and trim clips. Keep screws and clips organised.
3. Remove Water Shield: Peel back the vapour/water barrier to access the regulator and motor.
4. 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.
5. Disconnect Wiring: Unplug the motor electrical connector.
6. 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.
7. Install New Motor: Position the new motor, tighten mounting bolts, reconnect the wiring and test the window operation before reassembling the door.
8. 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.

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.

This direct-fit electric window motor is intended for the right front (passenger) door of the Peugeot 407. It restores smooth and reliable window movement and is commonly searched by part numbers 9646594480 and 9222Y9. Designed for use by professional workshops and competent DIYers, the unit provides a straightforward replacement for worn or failed motors in the vehicle’s window regulator assembly.

Features And Benefits

• Direct Replacement: Matches original fit and mounting points for Peugeot 407 passenger door applications.
• Restores Factory Function: Returns reliable up/down window movement and compatibility with the vehicle’s folding-in function.
• Ideal For Workshops And DIY: Clear identification by OE codes (9646594480 / 9222Y9) makes ordering and swapping efficient.

How It Works

The motor converts electrical energy from the vehicle into rotational motion that drives the window regulator mechanism. When the window switch is activated, the motor turns the geartrain that moves the regulator arm or cable, raising or lowering the glass. Proper operation depends on a sound electrical connection, an intact regulator mechanism and unobstructed window tracks.

Replacement Procedure

• Prepare: Park the vehicle on a flat surface, engage the handbrake and remove any obstructions from the work area.
• Disconnect Battery: Always disconnect the negative battery terminal before starting door work to avoid short circuits or accidental motor activation.
• Remove Door Trim: Carefully remove the interior door panel and any vapor/water barrier to access the regulator and motor.
• Support The Glass: Secure the window glass in position (tape to the door frame or use a helper) before detaching the regulator from the glass.
• Disconnect Motor: Unplug the electrical connector and remove the mounting bolts that secure the motor to the regulator/door shell.
• Install New Unit: Fit the replacement motor, reconnect the wiring, and initially run the motor to verify smooth travel and correct direction before final reassembly.
• Reassemble: Reattach the regulator to the glass, replace the vapor barrier and door trim, then reconnect the battery and perform final functional checks.

• Product Codes: 9646594480, 9222Y9
• Additional Numbers: NFP

Installation Recommendations

• Use Appropriate Tools: Avoid damaging plastic clips and door trim—use trim removal tools where possible.
• Check And Lubricate Tracks: Clean and lightly lubricate window channels and regulator slides with a suitable silicone or lithium-based grease to reduce friction and future wear.
• Inspect Regulator Mechanism: Replace or repair bent or worn regulator components to prevent premature motor failure after installation.
• Verify Electrical Connections: Ensure connector pins are clean and secure; check switch operation and fuse condition if the motor does not respond.
• Test Before Final Assembly: Cycle the window several times to confirm smooth operation and proper alignment before refitting the door trim.

Most Common Reasons For Failure

• Water Ingress And Corrosion: Moisture entering the door can corrode motor internals or connector contacts.
• Worn Brushes Or Commutator Wear: Over time electrical contacts inside the motor degrade, reducing torque or causing intermittent operation.
• Stripped Gears Or Mechanical Damage: Excessive force, a jammed regulator, or foreign debris can damage gear teeth or regulator components.
• Regulator Binding: Dirty or bent regulator tracks increase load on the motor and accelerate wear.
• Electrical Issues: Poor grounding, wiring damage or blown fuses can mimic motor failure—always check the circuit before replacing the motor.

How It Is Replaced

Replacement of the right front window motor typically involves these steps. Recommended for trained technicians or competent DIYers with basic electrical and trim-removal skills:

1. Disconnect the vehicle battery to avoid short circuits when working with door electrics.
2. Remove the interior door trim and vapor barrier to access the window regulator and motor.
3. Lower or support the glass as required, then detach the glass from the regulator (follow vehicle-specific clips and retainers).
4. Unplug the electrical connector from the motor and remove the mounting bolts securing the motor to the regulator or door frame.
5. Install the new motor, ensuring correct alignment of gears and splines; reconnect the electrical plug and temporarily reconnect the battery to test operation before final reassembly.
6. Reattach the glass to the regulator, check smooth travel through the full range, then reinstall the vapor barrier and door trim.

Installation Recommendations

• Always disconnect the battery before starting work on door electrics.
• Handle the glass carefully and support it to prevent dropping or chipping.
• Test motor function before reassembling the door trim to confirm correct wiring and mechanical engagement.
• Clean and lubricate the window channels and regulator sliders to reduce load on the motor and extend service life.
• Check the condition of door wiring and connectors for corrosion or damage and repair if necessary.

Why This Part Fails Most Often

Common causes of motor failure include water ingress and corrosion of electrical contacts, worn brushes or commutator inside the motor, broken or stripped gear teeth in the drive assembly, and excessive mechanical load caused by damaged regulator components or blocked window channels. Repeated jamming of the window or a seized regulator increases motor current draw and accelerates wear.
