Technical Information
- Manufacturer: Peugeot (Stellantis)
- Model: Peugeot 407 — Right Rear Door (Passenger Side)
- Product Codes: 9681337280, 9138N7
- Other Numbers: 9138V0
Function And Features
The lock assembly combines a mechanical latch with an electric actuator that operates the central locking. It secures the door in the closed position, permits remote locking/unlocking and interfaces with the vehicle’s locking rods and wiring harness. Proper operation ensures safe door closure, correct interior/exterior handle response and integration with child safety locking.
Replacement Guidance
Replacement involves the following steps common to Peugeot 407 rear door locks:
- Remove the interior door trim panel and any moisture shields to access the lock area.
- Disconnect the electrical connector and any locking/linkage rods from the actuator.
- Remove the mounting fasteners securing the lock to the door frame and extract the unit.
- Fit the new lock, reconnect rods and electrical connector, and secure all fasteners.
- Reinstall the door trim, then perform functional checks: cycle the central locking, test interior/exterior handles and verify child-lock operation.
Use suitable trim tools to avoid damage to clips and panels. When refitting, ensure linkage rods are correctly seated and that the latch aligns with the striker—misalignment causes poor latching and premature wear.
Installation Recommendations
- Work on a cold, dry day or in a controlled workshop to prevent moisture ingress during installation.
- Label linkage rods before removal to ensure correct reconnection. Photograph the assembly if necessary.
- Apply a small amount of lithium or white grease to moving metal-to-metal contact points; avoid excessive lubricant near electrical connectors.
- Check the wiring harness and connector for corrosion or damaged pins; repair any faults before fitting the new lock to prevent electrical issues.
- After installation, perform multiple locking/unlocking cycles and a road test to confirm secure operation.
Most Common Failure Reasons
- Actuator Motor Wear: Frequent use and age can wear the small electric motor and gearing, causing intermittent or complete failure of the locking function.
- Corrosion and Water Ingress: Moisture entering the door or lock body can corrode mechanical parts and connectors, leading to stiff or seized mechanisms and electrical faults.
- Broken Plastic Components: Internal plastic gears or latches can fracture over time, especially in cold climates or after impacts to the door.
- Linkage Damage or Detachment: Bent or disconnected linkage rods prevent the latch from operating correctly even if the actuator functions.
- Electrical Connector Issues: Loose, corroded or broken wires at the connector can interrupt power to the actuator and cause failure.
This lock is suitable for professional fitment in service garages as well as competent DIY repairs. Using the OEM reference numbers listed above helps ensure compatibility when sourcing the correct part for a Peugeot 407 right rear door.
