Description
Right Windshield Wiper Motor Bosch For Peugeot 407. Passenger Side.
This replacement right (passenger side) windshield wiper motor from Bosch is designed for the Peugeot 407 and provides reliable actuation of the wiper linkage and blades. It is a direct-fit electric motor assembly used to park and drive the wiper arms across the windshield. Many customers search for this part by product numbers such as 9656859880 or 3397020605—include these codes in your search to find an exact match.
Function: The wiper motor converts electrical power into rotational motion and transmits it through the linkage to move the wiper arms. A correctly functioning motor ensures smooth, consistent wiping strokes and a defined park position when switched off. Typical symptoms of a failing motor include intermittent movement, slow or labored wiping, unusual grinding or whining noises, or a complete loss of wiper movement on the passenger side.

Recommended Replacement Procedure
- Park vehicle with ignition off and remove negative battery terminal if desired for safety.
- Remove wiper arms from splines (mark their park position if needed) and lift off the cowl/grille to access the motor and linkage.
- Disconnect the electrical connector and detach the linkage from the motor output.
- Unbolt the motor assembly from its mounting points and remove it from the vehicle.
- Fit the new motor in reverse order: secure mounting bolts, reconnect linkage (ensure correct engagement and lubrication of splines), plug in the electrical connector and briefly reconnect battery to test function and park position before final reassembly.
- Reinstall cowl and wiper arms, set arms to correct park position and tighten securely. Perform a full function test in all wiper settings.
Installation Tips
- Mark wiper arm positions before removal to avoid incorrect alignment after fitting.
- Check and lightly grease splines and pivot points on the linkage to ensure smooth movement and to reduce wear.
- Verify the motor park position during test runs; incorrect park can indicate misaligned linkage.
- If the motor connector shows corrosion, clean or replace it to ensure reliable electrical contact.
Why This Part Usually Fails
Common causes of wiper motor failure include water ingress and corrosion (cowl area is exposed to rain and road spray), worn electrical brushes or commutator in the motor, seized or worn linkage and gears that overload the motor, and connector or wiring faults. Environmental exposure, heavy use and mechanical binding of the wiper linkage accelerate wear. Regular inspection and lubrication of linkage pivots can extend service life.
