Compatibility
Designed for Peugeot 406 Combi (estate) rear wiper applications. Buyers commonly search by part numbers 0390201556 or 6405G3 to confirm fitment. Suitable for workshops and home mechanics who need a replacement rear wiper motor that matches OE referencing.
Function And Failure Modes
The rear wiper motor converts electrical energy into rotational motion to drive the wiper linkage and blade across the rear window, providing clear rear visibility in rain and dirt. Typical failure causes include:
- Water ingress and corrosion of electrical contacts or internal geartrain
- Worn brushes or commutator inside the motor (common with high mileage)
- Damaged or seized gearbox within the motor assembly
- Broken or corroded connector pins and wiring
- Mechanical overload from seized linkage or frozen wiper arm
Service Life And When To Replace
Service life depends on use and exposure to the elements. In damp climates or on vehicles with damaged seals, motors may fail earlier due to corrosion. Replace the motor when the rear wiper stops moving, works intermittently, makes excessive noise, or smokes on operation.
Replacement Procedure (Summary)
Recommended for experienced technicians or competent DIYers. Typical replacement steps:
- Disconnect the vehicle battery before starting work to avoid short circuits.
- Remove the rear wiper arm (usually by lifting the cap at the pivot and removing the retaining nut).
- Remove the interior tailgate trim to access the motor and linkage—retain fasteners and clips safely.
- Disconnect the electrical connector and unbolt the motor from the tailgate assembly.
- Transfer any required linkage components or install the new motor and secure fasteners.
- Reconnect the connector, reassemble the trim, and reconnect the battery.
- Set the wiper park position by cycling the wiper and verifying correct resting position and sweep; adjust linkage if needed.
Installation Recommendations
- Always disconnect the battery before removing the motor or working on electrical connections.
- Inspect the wiper linkage and mounting points for wear or corrosion; replace damaged components to avoid premature failure of the new motor.
- Use appropriate hand tools and avoid over-tightening mounting bolts to prevent housing deformation.
- After installation, check for smooth operation and correct park position. Test under load (with water or in lowered temperatures) if possible.
Most Common Reasons The Part Fails
The most frequent causes of rear wiper motor failure are water ingress leading to corrosion, worn motor brushes, gearbox wear or seizing due to dirt, and electrical connector problems. Preventive care—ensuring seals and tailgate drains are clear—helps extend life.
Notes For Professionals
Search engines and procurement systems often find this part by its OEM numbers (0390201556, 6405G3) or by vehicle model. When listing or ordering, include both the Peugeot reference and part codes to improve discoverability.
