Description
Electric central lock for the right front door for Citroën C3 vehicles. 4 pins.
Product Overview
This electric central locking actuator for the Right Front Door is designed for Citroën C3 models. Built to restore reliable door locking and remote central locking function, this unit is a direct-fit replacement for worn or failed door lock actuators. Ideal for professional mechanics and competent DIY enthusiasts, the actuator accepts a 4‑pin electrical connector and interfaces with the vehicle’s door latch mechanism and central locking system.
Why Choose This Part
- Direct Replacement: Matches original mounting points and electrical connector for straightforward installation.
- OEM Reference Numbers Included: Customers often search by product codes 46983280 or 9136N7 — include these in your search to find this item quickly.
- Cost Effective Repair: Replacing the actuator restores central locking without replacing the entire latch assembly in most cases.
How It Works
The actuator converts electrical signals from the central locking system into mechanical motion to lock or unlock the door latch. When the lock/unlock signal is received, a small electric motor and internal gear train move the latch selector rod. Proper operation depends on the internal motor, gears, linkage, and a secure electrical connection via the 4‑pin connector.
Replacement Procedure (General Guide)
- Prepare: Park the car on a level surface, engage parking brake and remove the key from ignition.
- Safety: Disconnect the battery before starting to avoid short circuits and to prevent accidental activation of electrical systems.
- Door Trim Removal: Remove the inner door trim panel and vapor barrier to access the latch and actuator. Keep fasteners organized.
- Disconnect: Unplug the 4‑pin connector and detach any linkage or rods connected to the actuator. Note rod positions for correct reassembly.
- Remove Actuator: Unscrew the actuator from the latch assembly, install the new unit, reconnect linkages and wiring, then test operation before reassembling the door trim.
- Test: Reconnect the battery and verify locking/unlocking works from remote, door switch and central locking cycle. Ensure smooth mechanical movement and no binding.

Mounting Recommendations
Always disconnect the battery before removing or installing the actuator. Handle the actuator and door wiring harness carefully to avoid damaging plugs and plastic clips. Use the correct tools to remove door trim without breaking retainers. Before final reassembly, operate the lock several times to confirm correct mechanical linkage and electrical connection. If door drainage is compromised, repair seals to prevent water ingress into the actuator area.
Why This Part Commonly Fails
Common failure modes include motor wear, stripped internal gears, broken or fatigued linkage clips, and corrosion or water ingress that causes electrical faults or mechanical seizure. Frequent short trips with many cycles, exposure to moisture, and contaminated door cavities accelerate wear. Symptoms of failure are intermittent or complete loss of locking/unlocking function for the right front door, unusual noises from the door when operating locks, or the actuator running but not moving the latch due to broken internal gears.
Notes For Mechanics And DIYers
Keep the door interior clean and check drainage channels when replacing the actuator. If diagnosing intermittent faults, inspect wiring and connectors for corrosion or damage before replacing the actuator. Use the product codes 46983280 and 9136N7 when searching for compatible parts or cross-references to ensure you get the correct unit.
