Description
Overview
This electric tailgate lock actuator is intended for the rear hatch of the Citroën C3 Pluriel. The unit is an electro-mechanical actuator that locks and unlocks the tailgate as part of the vehicle’s central locking system, ensuring secure closure and proper alignment of the rear door.
Key Features
- Electric actuator for reliable tailgate locking and unlocking.
- Direct-fit replacement for Citroën C3 Pluriel when using matching part numbers.
- Designed for workshop replacement or experienced DIY installation.
- Restores central locking function and prevents water ingress when sealed correctly.
Symptoms And Common Failure Causes
Typical signs of a failing tailgate lock actuator include the tailgate not locking or unlocking with the remote or central locking, intermittent operation, unusual grinding noises when actuated, or the tailgate remaining stuck in a partially closed position. Failures are commonly caused by internal motor or gear wear, water ingress and corrosion, broken plastic components, or electrical faults such as damaged wiring and connectors.
Replacement And Installation Guide
Replacement is straightforward for competent technicians and experienced DIYers. General steps:
- Disconnect the vehicle battery to avoid short circuits and unintended locking events.
- Remove the tailgate interior trim panel to access the lock mechanism. Keep fasteners and clips organized.
- Disconnect the electrical connector and any linkage rods attached to the lock actuator.
- Unbolt the actuator from its mounting points and replace with the new unit, ensuring correct orientation and engagement with the striker.
- Reconnect wiring, reassemble trim, reconnect the battery and test central locking and remote operation several times to verify correct function.
If the lock does not operate after installation, inspect fuses, connectors and wiring harness for damage before assuming mechanical failure.
Maintenance Tips
Keep the tailgate seals and surrounding area clean and dry to reduce the risk of water entering the actuator. Periodically lubricate mechanical linkages with a suitable non-corrosive grease and check electrical connectors for corrosion. Address water leaks promptly to extend actuator life.
