Description
Electric lock for right rear door for Peugeot 407. Rear door on the passenger side.
High-quality electric door lock actuator designed for the right rear (passenger side) door of the Peugeot 407. This replacement lock restores reliable central locking and door latching function, eliminating symptoms such as the door failing to lock or unlock, intermittent operation, or noisy actuator movement. The unit is commonly referenced by part numbers and search codes listed below, which customers and technicians often use when locating the correct component.
Benefits & Application
Designed for professional automechanics and experienced DIY enthusiasts, this electric lock actuator provides a direct-fit replacement for worn or faulty rear right door locking units. It improves vehicle security and convenience by ensuring consistent operation of the central locking system. Ideal for Peugeot 407 vehicles with a conventional rear passenger door.
Technical Information
- Manufacturer: Stellantis / Peugeot
- Model: Peugeot 407 (Right Rear / Passenger Side)
- Product Codes: 9660699180
- Additional Numbers: 9138N7, 9138V0
How It Works
The electric door lock actuator converts electrical signals from the central locking system into mechanical movement to engage or release the door latch. When the actuator fails, the latch may not move fully, causing the door to remain unlocked, refuse to open, or produce clicking/grinding noises during locking cycles.
Common Symptoms Of Failure
- Door will not lock or unlock with central locking or remote.
- Intermittent operation — works sometimes and fails at other times.
- Audible grinding, clicking, or buzzing from inside the door panel.
- Complete loss of locking function on the right rear door.
Why This Part Fails
Failures are most commonly caused by wear of the internal electric motor and gears, moisture ingress leading to corrosion, or broken plastic components within the actuator mechanism. Repeated use over many years, exposure to water and salt (road conditions), and strain from misaligned latches increase the likelihood of failure.
Installation Recommendations
- Recommended For: Qualified automechanics and experienced DIYers comfortable working with door interiors and vehicle electrics.
- Basic Replacement Steps: Remove inner door trim and moisture barrier, disconnect the actuator electrical connector, unfasten the actuator mounting screws or bolts, detach linkage from the latch, fit the new actuator, reconnect linkage and wiring, test locking operation before reassembling the door.
- Safety Tips: Disconnect the vehicle battery or isolate the 12V supply before unplugging electrical connectors to prevent short circuits. Avoid pulling on wiring harnesses; handle the door trim and clips carefully to prevent damage.
- Testing: Verify full lock/unlock travel and listen for smooth motor operation. Check manual lock function and central locking operation from both remote and interior switches.
- Additional Advice: Inspect door latch alignment and wiring harness for corrosion or damage while the door is open. Apply suitable lubricants to mechanical latch points if necessary.
This electric lock actuator is frequently searched by its part numbers (9660699180, 9138N7, 9138V0) — using these codes speeds up identification and ensures you obtain the correct replacement for the Peugeot 407 right rear (passenger side) door.
