Technical Information
- Manufacturer: Stellantis (Citroën/Peugeot)
- Model: Citroën C4 5‑Door (Right Rear Door)
- Product Codes: 9681337080, 9138N5
- Other Numbers: 9660700480E03, 9138T6
Function And Features
The unit combines an electric actuator with the mechanical latch to operate central locking and secure the door striker. When energized by the vehicle’s central locking system, the actuator moves internal linkages to lock or unlock the door. The assembly typically includes the electrical connector, mounting points and the latch mechanism — replacement restores both electrical actuation and mechanical locking function.
Compatible Vehicles
Designed for Citroën C4 5‑door models requiring the above part numbers. Compatibility is usually verified by the product code printed on the original unit; many customers search directly by these numbers when replacing the right rear door lock.
Symptoms Indicating Failure
- Right rear door fails to lock or unlock with central locking commands.
- Intermittent locking operation or delay before the latch moves.
- Audible grinding or whining from inside the door when operating the lock.
- Door remains mechanically stuck or does not latch properly.
- Electrical faults such as blown fuses or moisture-caused shorting at the connector.
Why The Part Most Often Fails
Failures are most commonly caused by water ingress and corrosion, wear of plastic gears or actuators, mechanical damage from door impacts, and broken or fatigued linkage cables. Long-term exposure to dirt and moisture accelerates wear and can cause the motor or internal switches to fail. Connector corrosion and wiring fatigue at the door harness are frequent secondary causes.
Installation Recommendations
Before starting any work on the door electrics, disconnect the vehicle battery to avoid short circuits and unintended airbag/vehicle system triggers. Typical replacement steps:
- Remove the inner door trim and moisture barrier carefully to access the lock assembly.
- Disconnect the electrical connector and any linkages or rods attached to the latch.
- Unbolt the lock assembly from the door and remove the unit from the latch side.
- Install the new lock assembly, reconnect rods and the electrical connector, then test central locking operation and latch function before reassembling the door trim.
- Check and lubricate mechanical contact points with an appropriate lubricant to ensure smooth operation and reduce future wear.
Re-test the door several times with the vehicle locked/unlocked and with the key/remote to ensure correct operation before finishing reassembly.
Notes For Professionals And DIYers
Part numbers are commonly used to locate the exact replacement; the codes listed in the Technical Information section match units found on compatible Citroën C4 right rear doors. Replacement is straightforward for experienced technicians but requires careful handling of the door trim and connectors. Inspect the door wiring harness and rubber grommet for damage or water entry while the door is open.
