Description
Electric window regulator motor for the right front window for PEUGEOT 407. With electric folding-in function to the vehicle. Front Passenger Door.
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.
Technical Information

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.
Search By Part Number: If you are replacing the component, use product codes 9646594480 or 9222Y9 to confirm correct fitment for the Peugeot 407 right front window.
