This direct-fit electric window motor is designed for the right front (passenger) door of the Peugeot 407. Built to restore reliable up-and-down movement and to support the electric folding-in function indicated for this unit, it is a practical replacement for worn or failed original motors. Ideal for professional workshops and experienced DIY mechanics, the motor matches common OE references 9663036580 and 9222Y9, making it easy to find in parts lists and search engines.

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.
