Compatibility And Application
Fits the right rear door of Peugeot 407 models. Verify the pictured connector type and mounting points against the vehicle, as door trim and locking modules can vary by equipment level and production date. This part is typically used where the central locking fails to operate the right rear door or where mechanical locking is impaired.
Installation Recommendations
- Disconnect the negative battery terminal before working on electrical components to prevent short circuits and unintended airbag deployment.
- Remove the inner door trim and water shield carefully to access the lock assembly. Keep fasteners and clips organized for reassembly.
- Unplug the electrical connector and detach the lock linkage/rods from the latch mechanism. Note the position of retaining clips for correct refitment.
- Remove the mounting bolts, replace the lock assembly, refit linkage and connector, then test central locking and manual operation before reinstalling the door trim.
- Check for damaged or corroded wiring and lubricate moving linkages with a light spray lubricant suitable for door mechanisms.
Typical Failure Modes And Why They Occur
- Actuator Motor Wear: Repeated cycles and aging can wear brushes or small electric motors inside the actuator, causing intermittent or complete failure.
- Plastic Gear/Pawl Damage: Internal plastic components can fracture under load or with age, preventing proper lock movement.
- Water Ingress And Corrosion: Moisture entering the lock cavity leads to corrosion of mechanical parts or shorting of electrical contacts—common in high-humidity or coastal environments.
- Linkage Or Clip Breakage: Bent or broken rods and retainer clips prevent transmission of motion from the actuator to the latch.
- Electrical Faults: Damaged wiring, poor connector contacts, or blown fuses in the central locking circuit can mimic a failed lock.
Symptoms of a failing lock include noisy operation, intermittent locking/unlocking, inability to lock or unlock the door with the remote or interior switch, and a door that does not fully latch. Lifespan varies with use and environment; failures often appear after several years of service or higher mileage, especially where moisture or debris accelerate wear.
