Application And Fitment
Fits rear wiper assemblies on Citroën C8 and Peugeot 807 (factory models produced in the 2000s). Check the listed product codes when searching — this part is frequently referenced by its OEM numbers.
Function
The rear wiper motor converts vehicle electrical power into the mechanical motion required to sweep the rear wiper arm across the glass. It incorporates a small gear drive and output linkage that moves the wiper arm and ensures the blade parks correctly at the rest position. A secure electrical connector provides power and sometimes a park/position signal to the vehicle wiring.
Common Causes Of Failure
Typical failure modes include water ingress and corrosion of the motor housing or gearbox, worn brushes or commutator, seized or damaged output gear, deteriorated seals, and electrical faults such as poor grounding or connector corrosion. Problems often appear after many years of exposure to weather, salt and dirt, or when the wiper linkage seizes and places extra mechanical load on the motor.
Replacement Frequency
Service life varies with use and environment; many rear wiper motors remain reliable for several years, while in harsh climates or with heavy use failures may appear after around 8–12 years. Regular inspection of the wiper arm, linkage and gaiter helps spot early signs of wear or water ingress.
Installation Recommendations
Installation should be carried out by a trained technician or an experienced DIY mechanic. Typical replacement steps:
- Open the tailgate and remove the interior trim to access the motor housing.
- Remove the wiper arm (undo the retaining nut and remove the arm from the spline).
- Disconnect the electrical connector and detach any linkage or grommet around the motor output.
- Unscrew the motor mounting fasteners and remove the old motor assembly.
- Fit the new motor, secure mounting fasteners, reconnect linkage and electrical connector, and replace the washer grommet if required (ref. 6405EQ available separately).
- Test the wiper and washer function before reassembling the trim; ensure the wiper parks correctly and operates without binding.
Typical workshop time: approximately 30–60 minutes depending on vehicle access and experience. Use basic hand tools and take care with trim clips to avoid damage.
