Description
Electric central locking actuator for the left rear door. For PEUGEOT 3008 first generation. Door behind the driver.
Description
This used electric central locking actuator (part numbers 9800623780 / 9137T8) is a direct-fit component for the left rear (driver side rear) door of first generation Peugeot 3008 models. The actuator drives the door latch and responds to the vehicle’s central locking signals to lock and unlock the door. It is a commonly replaced item during repairs to the locking system and is often searched by OE number, making it easy to find for professional technicians and DIY enthusiasts.
Technical Information
- Manufacturer: Stellantis / Peugeot
- Model: Peugeot 3008 I (First Generation)
- Product Codes: 9800623780
- Additional Numbers: 9137T8
Compatibility
Fits Left Rear Door (door behind the driver) of Peugeot 3008 first generation models. Always check the part number (9800623780 / 9137T8) against the unit you are replacing to ensure correct fitment.
Function And Common Symptoms
The actuator converts electrical signals from the central locking system into mechanical movement that operates the door latch. Typical symptoms of a failing actuator include intermittent or complete inability to lock/unlock the affected door, noise from inside the door cavity when operating the locks, or the door not latching reliably. Because the actuator is integrated with the latch mechanism, problems here affect door security and convenience.
Why The Part Fails Most Often
- Water ingress and corrosion in the actuator motor or electrical connector causing poor contact or motor failure.
- Worn plastic gears or mechanical linkage inside the actuator breaking after years of use.
- Contaminated or seized latch mechanism increasing load on the motor and causing premature failure.
- Electrical issues such as damaged wiring or connectors, or weakened motor windings from heavy cycling.
Installation Recommendations
- Disconnect the negative battery terminal before starting work to avoid short circuits and electrical damage.
- Remove the door trim panel carefully using trim tools to avoid damaging clips and the door card.
- Locate and disconnect the actuator electrical connector and any linkages to the latch (note orientation for reassembly).
- Remove fasteners securing the actuator, swap in the replacement unit, and reattach linkages and connector. Ensure linkages are correctly seated and move freely.
- Before refitting the door card, test the lock operation with the ignition on to confirm correct function.
- Lubricate latch pivots and check inner door seals for water ingress to reduce risk of future failure.
- Recommended tools: trim removal kit, Torx/screwdriver set, pliers, multimeter for quick electrical checks.
Notes For Professionals And DIYers
This part is often sought by technicians under OE numbers 9800623780 and 9137T8, so include these in searches and service records. When replacing, inspect the door wiring harness and connector for corrosion or broken wires, and ensure the door’s drainage/seals are intact to avoid repeat failures. After installation, verify smooth mechanical movement and quiet motor operation.
Service Life
Service life depends on environment and usage. Actuators can fail after several years, commonly appearing between roughly 5–12 years of service, especially in vehicles exposed to moisture, road salt, or heavy use.
Purchase Recommendation
If your Peugeot 3008 I exhibits locking faults on the left rear door, replacing the actuator with the correct part (9800623780 / 9137T8) is a cost-effective repair that restores door security and convenience. Add the part to your cart to get the unit delivered ready for fitting.
