Function And Fitment
The rear wiper motor converts electrical input into rotational motion for the rear wiper arm. It is mounted on the tailgate and connected to the wiper linkage; proper operation ensures the rear window is wiped clean for improved visibility. This unit fits the Peugeot 407 SW rear hatch and is commonly ordered using the product/part numbers listed above to ensure exact compatibility.
Common Failure Modes
Rear wiper motors typically fail due to moisture ingress that causes corrosion, worn commutator brushes or bearings, stripped internal gears, or electrical connector/circuit faults. Symptoms include no movement, intermittent operation, slow or noisy motion, grinding sounds, or a wiper arm that stops in the wrong position. Heavy snow, blocked wiper movement and long-term exposure to road salt accelerate wear.
Installation Recommendations
Installation is straightforward for a trained technician or an experienced DIYer. General steps:
- Support the tailgate and remove interior trim to access the motor.
- Remove the wiper arm (mark its rest position) and disconnect the electrical connector.
- Unbolt the motor from the tailgate and detach the linkage from the motor spline.
- Install the new motor, reattach the linkage in the marked position, tighten mounting bolts to manufacturer torque, reconnect the electrical plug and refit interior trim.
- Test operation through all park positions and ensure the wiper parks correctly. Apply light grease to splines if needed and ensure connectors are dry and protected against corrosion.
Why Replace
Replace the rear wiper motor when the wiper is non-functional, moves intermittently, produces abnormal noise, or if the motor overheats. Replacing the motor restores clear rear visibility, reduces the risk of further damage to the linkage, and ensures safe reversing and poor-weather driving.
Ordering tip: Many mechanics and DIY customers search by OEM numbers (9646500880, 54906212, 6405R1) to find the correct rear wiper motor for Peugeot 407 SW quickly—include these codes when searching to speed up part identification.
