Function and Fitment
The electric window motor provides the rotational force required to move the window regulator mechanism. It is designed to fit the left rear door (driver-side rear) on Peugeot 407 models equipped with power windows. When installed correctly, the motor interfaces with the regulator assembly and the vehicle electrical connector to restore normal window operation.
How To Replace
- Disconnect vehicle battery negative terminal to avoid short circuits.
- Remove the inner door trim panel and any vapor barrier carefully to access the regulator and motor.
- Lower or support the glass as required to access fasteners securing the motor/regulator assembly.
- Disconnect the electrical connector from the motor and remove the mounting bolts.
- Remove the motor from the regulator; transfer any necessary brackets or clips to the new motor if applicable.
- Fit the new motor, secure bolts, reconnect the electrical connector and temporarily reconnect the battery to test operation before reassembling the door.
- After confirming correct operation and window alignment, reassemble the vapor barrier and door trim panel.
Installation Recommendations
- Test the motor electrically before final reassembly to ensure proper rotation and response in both directions.
- Inspect the regulator (gears, cables, sliders) and window tracks for wear, corrosion or binding; replace or lubricate as needed to prevent premature motor failure.
- Use dielectric grease on electrical connectors to reduce the risk of corrosion and poor contact.
- Keep mounting surfaces clean and use the original fasteners where possible; ensure bolts are snug but avoid over-tightening.
- Align the glass and regulator properly to avoid excessive load on the motor during operation.
Most Common Failure Reasons
- Wear of internal motor brushes or bearings after long service life, reducing torque output.
- Water ingress and corrosion inside the door causing electrical faults or seized components.
- Regulator wear, damaged cables or seized sliders that overload the motor.
- Debris or misaligned window tracks creating binding and increased current draw.
- Intermittent electrical connections at the plug or a damaged wiring loom in the door.
Searching by part number (9646595680, 922386) is common and helps ensure correct fitment for the Peugeot 407 left rear door. Follow safe workshop practices when performing the replacement, and verify smooth regulator movement before completing the job.
