Description
Left Rear Wing Door Lock For Citroën Berlingo And Peugeot Partner I And II
This replacement left rear wing door lock is designed for Citroën Berlingo and Peugeot Partner models (Generations I and II). It restores secure door latching and reliable central locking operation, making it an essential spare part for professional workshops and DIY enthusiasts. The unit is suitable for vehicles that use mechanical-electrical locking actuators integrated with the door latch mechanism and is commonly searched by the OEM code 8726E7.
Key Benefits
High-quality construction ensures long service life under typical urban and commercial use. Direct-fit design simplifies installation and reduces workshop labor time. Compatible with central locking systems, this lock delivers reliable bolt engagement and prevents water ingress and door misalignment when fitted correctly.
Function And Typical Faults
The door lock secures the door in the closed position and interfaces with the vehicle’s central locking actuator and door microswitches. Common failure modes include worn mechanical latch components, corrosion from moisture ingress, broken actuator linkage, and electrical connector issues causing intermittent or no locking/unlocking. In commercial and high-mileage vehicles, mechanical wear or latch jamming is the most frequent cause for replacement.
How The Part Is Replaced
- Prepare Vehicle: Park on level ground, set the handbrake and, if available, support with wheel chocks.
- Safety First: Disconnect the battery before starting work to prevent short circuits and false triggers of the central locking system.
- Remove Interior Trim: Take off the inner door panel and vapor barrier to access the lock mechanism. Keep screws and clips organized.
- Disconnect Electrical Connector: Unplug the lock actuator wiring harness and any microswitch connectors.
- Unbolt Lock Assembly: Remove the bolts or rivets securing the lock to the door and extract the old unit, noting the linkage and cable routing.
- Install New Lock: Position the replacement lock, secure fasteners, reconnect linkage and cables, and plug in the electrical connector.
- Test Operation: Reconnect the battery and test locking/unlocking, both manually and via central locking, before refitting the trim. Adjust striker alignment if necessary.
- Refit Trim: Reinstall the vapor barrier and door panel, ensuring all clips and screws are secure.
Installation Recommendations
- Always disconnect the vehicle battery before removing the lock to avoid electrical damage.
- When replacing, compare the new unit with the old one to confirm identical connectors and mounting points.
- Lubricate moving latch points with a suitable long-life grease after installation to reduce wear and noise.
- Check door striker alignment and adjust if locking is stiff or the door does not close flush.
- Use correct hand tools and torque values for fasteners to avoid deformation of the lock housing or door sheet metal.
Common Reasons For Failure
- Corrosion From Moisture: Water ingress accelerates mechanical wear and can seize moving parts.
- Mechanical Wear: High mileage and heavy use cause latch components to wear and lose engagement precision.
- Actuator Or Linkage Failure: Broken plastic linkages or failing electric actuators lead to loss of remote locking function.
- Contamination: Dirt and debris entering the latch can obstruct mechanism movement.
