Description
Electric motor for the right rear window for PEUGEOT 407 vehicles. Rear Door (Passenger Side).
This window regulator motor is designed for the right rear (passenger‑side) window of the Peugeot 407 and is commonly searched by its part numbers. It is a direct‑fit electric motor intended to operate the window regulator mechanism, restoring smooth and reliable up/down movement. Suitable for professional workshops and DIY mechanics who need a replacement unit that matches original equipment fitment.
The motor drives the window regulator gearbox and converts electrical input from the window switch into the mechanical movement of the glass. Typical symptoms indicating a faulty motor include no movement from the switch, intermittent operation, grinding or clicking noises from inside the door, or the window moving very slowly. Because the part is often identified by its reference numbers, check the product code before ordering.
Replacement is straightforward for a trained mechanic or competent DIYer: remove the door trim and plastic moisture barrier, support the glass in the closed position (or remove and secure it), disconnect the electrical connector, unbolt the motor/regulator assembly, and replace the motor or complete regulator as required. Reassemble in reverse order and test the window operation before refitting the trim. Use care when handling the glass and follow standard safety procedures to avoid injury or damage.
Typical Service Life And Failure Causes: Under normal use the motor can last many years, but lifespan depends on usage frequency, exposure to moisture, and regulator condition. Common causes of failure are worn motor brushes or commutator, water ingress and corrosion, damaged or stripped gears in the regulator, and mechanical binding of the regulator mechanism. Regularly checking door drainage and avoiding forcing the window can extend service life.

Installation Recommendations
- Work On A Cold, Stable Surface And Disconnect The Battery Before Starting.
- Support Or Secure The Glass To Prevent Dropping When The Regulator Is Removed.
- Inspect Regulator Tracks, Cables And Mounting Points; Replace Any Worn Components To Prevent Early Failure Of The New Motor.
- Clean And Lightly Lubricate Moving Parts; Apply Dielectric Grease To Electrical Connectors To Protect Against Corrosion.
- Test Full Window Travel And Auto‑Functions (If Present) Before Reinstalling Door Trim.
Reason For Most Common Failure
The most frequent reasons for motor failure are water ingress and corrosion inside the door, which attack electrical contacts and the motor windings, and mechanical wear of brushes or plastic gears. Regulator misalignment or seized guide channels also increase motor load and accelerate wear. Addressing the underlying regulator issues during replacement reduces the chance of repeat failure.
