Description
Electric central locking actuator for the left front door of Citroën C3. Driver’s door. 5 pins.
High-quality replacement door lock actuator for the left front door of the Citroën C3, identified frequently by product numbers 46982980 and 9135N0. This electric central locking unit controls locking and unlocking of the driver’s door and integrates with the vehicle’s central locking system. Ideal for professional mechanics and DIY enthusiasts searching by part number — a direct-fit component designed to restore reliable door operation and central locking function.
Technical Information
- Manufacturer: Citroën (Stellantis)
- Model: Citroën C3
- Product Codes: 46982980, 9135N0
- Other Numbers: 5-pin electrical connector
Fitment
Designed for the Left Front Door (Driver’s Side) of Citroën C3 vehicles equipped with a 5-pin connector. Check connector type and mounting points to confirm fitment before installation. This unit is commonly searched and identified by its OEM codes (46982980, 9135N0).
Function
The actuator is an electromechanical unit that operates the door latch mechanism as part of the central locking system. When a lock/unlock signal is received from the remote or central locking command, the actuator moves the latch to lock or release the door. It may also provide microswitch feedback to the vehicle control system about door status.
Replacement Procedure
- Disconnect the vehicle battery to avoid short circuits and unintended activation.
- Remove the interior door trim panel and vapor/water barrier to access the lock mechanism.
- Disconnect the 5-pin electrical connector from the actuator.
- Unfasten retaining screws or clips securing the actuator and detach any linkage rods from the latch.
- Install the replacement actuator by reversing the removal steps: secure the unit, reconnect linkages and electrical connector, re-fit door trim, and reconnect the battery.
- Test locking and unlocking from the remote, central locking switch, and mechanical handle to ensure full function.
Installation Recommendations
- Always disconnect the battery before starting work to prevent electrical damage and accidental activation.
- Handle internal linkages and plastic clips carefully to avoid breakage; replace damaged clips during reassembly.
- Inspect connector pins and wiring for corrosion or damage — clean contacts and use dielectric grease if needed to improve contact and prevent future corrosion.
- Ensure the actuator moves freely before reassembly; do not force the mechanism. Lubricate latch pivot points with suitable lubricant if required.
Common Failure Causes
Door lock actuators commonly fail due to water ingress and corrosion, worn internal gears or motor wear, damaged or corroded electrical connectors, and mechanical strain from misaligned door latches. Symptoms include door not locking or unlocking, intermittent operation, noisy or sluggish movement, or the central locking system reporting a faulty door sensor. Addressing water seals and connector corrosion during replacement reduces the risk of repeat failures.
Why Choose This Part
Searching by OEM code (46982980 / 9135N0) helps ensure you receive the correct replacement. This actuator restores reliable locking function and is suitable for professional workshops and competent DIY installers who follow safe installation practices.
