Description
Electric central locking door lock for the right front door of the PEUGEOT 307 CC. Passenger side. 6-pin connector.
Replacement Electric Door Lock Actuator designed for Peugeot 307 CC vehicles. This 6-pin right-front (passenger side) central locking unit restores reliable locking and unlocking, ensures proper door latching and secures the vehicle. Ideal for professional workshops and experienced DIYers looking for a direct-fit solution listed under common part numbers (52229780, 9136Q1). The unit is built for OE-style fitment and connects via the standard 6-pin plug used on many mid-2000s Peugeot 307 CC models.
Function And Symptoms
The door lock actuator controls the mechanical locking and unlocking of the door as part of the central locking system. Typical symptoms of a failing actuator include intermittent or complete loss of locking/unlocking on the affected door, unusual noises (grinding, whining or clicking) when operating the locks, a door that does not latch properly, or the central locking working for other doors but not the affected side. Failure is often caused by worn gears in the actuator motor, broken plastic components, water ingress leading to corrosion, or faulty microswitches inside the unit.
Replacement Procedure
Basic replacement steps (for trained mechanics or competent DIYers):
- Disconnect the negative battery terminal before starting work to avoid short circuits and protect vehicle electronics.
- Remove the interior door trim panel and any vapor barrier carefully to access the lock/latch assembly.
- Disconnect the 6-pin electrical connector and any linkages or rods attached to the latch mechanism.
- Unbolt the lock/latch assembly from the door and remove the old unit.
- Install the replacement unit, reconnect linkages and the 6-pin connector, and secure all fasteners to the manufacturer’s torque recommendations.
- Reconnect the battery, test locking/unlocking functions (remote and manual) and check door latching before reassembling the door trim.
Installation Recommendations
- Always disconnect the battery before removing electrical components.
- Handle plastic clips and door panel trim carefully to avoid breakage; use proper trim tools.
- Inspect and, if necessary, lubricate door latch linkages and locking plunger with an appropriate lubricant to reduce wear and noise.
- Ensure the 6-pin connector is clean and fully seated; check wiring for abrasion or corrosion while the door panel is removed.
- Test the lock function thoroughly before final reassembly to confirm correct operation.
Most Common Failure Causes
- Wear of small plastic or nylon gears inside the actuator motor, especially after many cycles.
- Water ingress or moisture leading to corrosion of contacts or motor components.
- Broken or fatigued linkage rods and clips that prevent proper actuation.
- Electrical faults such as damaged wiring, corroded connectors, or failed internal microswitches.
