Description
Electric Central Locking Actuator – Left Front Driver’s Door
For CITROEN BERLINGO, XANTIA and PEUGEOT PARTNER I and II, PEUGEOT 406
Rectangular Two-Row Connector
Product Overview
This electric central locking actuator is designed for the left front (driver’s) door of selected Citroën and Peugeot models. It replaces the door lock mechanism responsible for locking and unlocking via the vehicle’s central locking system. Commonly searched by product code 9135H8, this unit features a rectangular two-row electrical connector and is suitable for workshops and DIY mechanics who need a direct-fit replacement part.
Applications
Fits the following models (examples): Citroën Berlingo, Citroën Xantia, Peugeot Partner I, Peugeot Partner II, Peugeot 406. Intended for left front (driver) door central locking application. Always verify physical connector shape and mounting points against the existing part before installation.

Installation Recommendations
- Disconnect the negative battery terminal before starting to avoid short circuits and accidental airbag deployment.
- Remove the door trim panel using appropriate trim tools to avoid damaging clips.
- Disconnect the rectangular two-row electrical connector and any rod/linkage from the actuator. Note the positions of retaining clips and washers.
- Unscrew the actuator mounting bolts and remove the old unit. Compare the new actuator to the old one to ensure identical connector orientation and mounting points.
- Fit the new actuator, reconnect linkages and the electrical connector, then loosely fit mounting bolts. Operate the locking mechanism by hand or using the vehicle controls to confirm correct alignment, then tighten bolts to the manufacturer’s torque specifications.
- Reinstall door trim, reconnect the battery, and test central locking from both remote and interior switches. Check that the door latches properly and that there is no unusual noise or binding.
Most Common Failure Causes
Actuators of this type typically fail because of water ingress and corrosion of internal components or connectors, worn electric motor brushes, broken plastic gears inside the actuator, or failed micro-switches that detect lock position. Mechanical wear on linkages and rod clips or damage from slammed doors can also lead to malfunction. Vehicles regularly exposed to moisture, road salt, or heavy use are more prone to premature failure.
Notes For Mechanics and DIYers
When replacing the actuator, inspect door linkages, latches, and the electrical connector for corrosion or play. Lubricate mechanical joints with suitable grease and ensure the wiring harness is intact. This part is intended as a direct replacement for the left front driver’s door central locking function — confirm connector type (rectangular two-row) and mounting arrangement before ordering.
