Description
Electric central locking actuator for the right rear door for PEUGEOT 307. Right Rear Door (Passenger-Side Rear).
Replace faulty central locking with a direct-fit electric door lock designed for Peugeot 307. This unit operates the latching and locking functions of the right rear door, integrating with the vehicle’s central locking system to lock/unlock the door via remote, key or interior lock switches. The actuator assembly transfers motion from the electric motor to the mechanical latch and linkages, ensuring secure closure and reliable unlocking every time.
Key Benefits
– Direct fit for Peugeot 307 with the OEM code 9138G0, commonly searched by mechanics and DIY enthusiasts.
– Restores proper locking and unlock functions without needing to replace complete door modules.
– Improves vehicle security and passenger convenience by re-establishing central locking control on the rear passenger-side door.
Function And Symptoms
The actuator converts electrical signals from the central locking system into mechanical movement that operates the door latch. Typical symptoms of a failing unit include: noisy or weak motor sounds inside the door, door that does not lock or unlock with the central locking, intermittent operation, or a door that appears stuck and requires manual manipulation. In some cases a faulty actuator can trigger a central locking fault or cause uneven locking across doors.
Replacement Procedure (Overview)
Replacement requires basic workshop tools and moderate skill. Typical steps:
- Disconnect the battery before starting.
- Remove interior door trim and any moisture barriers to access the lock assembly.
- Disconnect electrical connector and detach locking rods/linkages from the actuator.
- Unbolt or unclip the old lock/actuator from the door shell and withdraw the unit.
- Install new actuator, reconnect linkages and electrical connector, then test operation before reassembling the door trim.
- Reassemble trim and verify seal integrity to prevent future water ingress.
Installation Recommendations
– Always Disconnect The Battery Before Demounting Or Mounting Electrical Components.
– Follow The Vehicle Manufacturer’s Fastening Torques And Reassembly Order Where Available.
– Check And Lubricate Linkage Ball Joints And Latch Points With Appropriate Grease To Reduce Wear.
– Inspect Door Seal And Drain Channels For Blockage To Prevent Water From Reaching The Actuator.
– After Installation, Cycle The Central Locking Several Times To Confirm Smooth Operation.
Common Failure Causes
– Water Ingress: Moisture Reaching The Actuator Causes Corrosion Or Electrical Shorting.
– Mechanical Wear: Plastic Gears Or Linkage Mounts Wear Or Break Over Time.
– Motor Fatigue: The Small DC Motor Loses Torque After Years Of Use Or Repeated Heavy Loads.
– Connector Or Wiring Faults: Broken Wires Or Corroded Connectors Lead To Intermittent Operation.
– Age And High Mileage: Units Often Fail After Several Years Of Service, Especially On Cars Frequently Exposed To Wet Conditions.
