Function And Benefits
The actuator is an electric motor-driven unit that operates the central locking mechanism and the door latch. It converts electrical signals from the central locking system into mechanical movement of the latch and linkage. Replacing a worn or failed actuator restores full locking/unlocking operation, eliminates grinding or intermittent locking, and prevents the door from failing to latch securely.
Typical Symptoms Of A Faulty Actuator
- Door Does Not Lock Or Unlock With Central Locking Commands
- Intermittent Operation Or Delayed Response
- Audible Grinding, Clicking Or Struggling Noises Inside The Door
- Door Fails To Latch Or Pops Open Slightly While Driving
How The Part Is Replaced (Overview)
Replacement is straightforward for an experienced technician or competent DIYer with basic tools. Typical steps:
- Remove The Inner Door Trim And Moisture Barrier To Access The Lock Module.
- Disconnect The Electrical Connector From The Actuator.
- Release Or Unclip Linkages Between Actuator And Door Latch (Note Orientation For Reassembly).
- Remove Mounting Screws Or Rivets Securing The Actuator And Extract The Unit.
- Install The New Actuator, Reconnect Linkages And Electrical Connector, Refit The Moisture Barrier And Door Trim.
- Test Central Locking Operation On All Doors And Verify Proper Latch Function.
Installation Recommendations
- Disconnect The Battery Before Starting Work To Avoid Short Circuits And Accidental Locking.
- Note The Exact Position Of Linkage Rods And Clips To Ensure Correct Reassembly.
- Inspect Wiring And Connector For Corrosion Or Damage; Clean Contacts If Necessary.
- Replace Any Broken Clips Or Fasteners During Reassembly To Avoid Future Rattles Or Misalignment.
- After Installation, Cycle The Central Locking Several Times And Check Door Latch Engagement At Different Lock Positions.
- Use Correct Torque On Fasteners And Ensure The Moisture Barrier Is Properly Seated To Prevent Water Ingress.
Why This Part Fails Most Often
- Water Ingress And Corrosion From Damaged Moisture Barrier Leading To Motor Or Switch Failure.
- Mechanical Wear Of Internal Gears Or Plastic Components Causing Grinding And Loss Of Drive.
- Broken Or Worn Linkage Clips And Rods That Place Extra Load On The Actuator.
- Electrical Issues Such As Shorted Wiring, Corroded Connectors Or Intermittent Power Supply.
- Frequent Use Over Many Years Accelerating Wear—Failure Is Typically Progressive, Not Sudden.
Practical Tips For Mechanics And DIYers
- When Replacing One Actuator, Inspect The Opposite Door And Other Locking Actuators—Similar Age Components Often Fail Soon After.
- Lubricate Moving Linkage Points And The Latch With Suitable Grease To Reduce Load On The Actuator.
- Keep A Record Of Part Codes (9681337380 / 9137K8 / 9137Q7) For Future Reference; Customers Often Search By These Numbers.
This actuator is aimed at professional workshops and competent DIY enthusiasts carrying out maintenance and repairs on Peugeot 407 vehicles. The listed OEM references help ensure you order the correct replacement part for the left rear (driver’s side) door.
