Stellantis CITROEN PEUGEOT 9660700680 9136EV
Reliable replacement electric door lock for the right front (passenger) door of the Citroën C4 Coupe (first series). Ideal for mechanics and DIY enthusiasts searching by product code 9660700680 or 9136EV. The unit operates with the vehicle’s central locking system to lock and unlock the door, working together with linkage rods and the door latch mechanism. This part restores secure locking, eliminates intermittent central-locking failures, and is commonly used when the original actuator or latch assembly shows mechanical wear or electrical faults.
Technical Information
- Manufacturer: Stellantis / Citroën
- Model: Citroën C4 Coupe (First Series) — Right Front Passenger Door
- Product Codes: 9660700680, 9136EV
- Additional Numbers: Commonly referenced by OE Code 9660700680 / Internal Code 9136EV
Compatibility
Designed for Citroën C4 Coupe first-generation models (front right/passenger door). Buyers frequently search using the product codes above—verify the part number against the existing unit to confirm fitment. This unit is the electric central locking actuator/latch assembly for the passenger door.
Installation Recommendations
- Disconnect the battery before starting to avoid short circuits and to protect vehicle electronics.
- Remove the interior door trim using plastic trim tools to avoid damage to clips and panels.
- Carefully disconnect electrical connectors and unclip or unscrew the linkage rods from the lock mechanism—note their orientation for correct reassembly.
- Unbolt the lock assembly from the door and replace with the new unit. Reconnect linkages and electrical connector, then test operation (lock/unlock, central locking, and manual key operation) before refitting the door trim.
- Lubricate moving points lightly with appropriate lock lubricant and ensure water seals are intact to reduce future ingress of moisture.
- If any coding or adaptation is required by the vehicle (rare for simple door locks), perform according to manufacturer procedures. Always follow safety guidelines and torque specifications in the vehicle repair manual.
Why This Part Usually Fails
- Plastic Gear Or Actuator Wear: Internal plastic gears and small electric motors wear over time, causing intermittent or complete failure.
- Moisture And Corrosion: Water ingress through damaged door seals can corrode contacts or seize mechanical components.
- Mechanical Fatigue: Linkage clips, rods, or latch components can bend or break after years of use or forceful operation.
- Electrical Issues: Connector corrosion or wiring fatigue can interrupt power to the actuator, leading to unreliable locking.
- Age And Mileage: Typical life depends on use and environment; parts often fail after many years of service, especially in salty or wet climates.
Notes For Mechanics And DIYers
This listing describes a used replacement door lock supplied as-is. It is commonly sought by technicians and independent enthusiasts who identify parts by OE numbers (9660700680 / 9136EV). Inspect the part visually before installation and verify mechanical linkages align correctly during reassembly. Testing the central locking operation prior to final reinstallation of trim saves time and prevents rework.
Purchase Advice
Searching by the product codes 9660700680 or 9136EV will quickly locate this part. Replacing a faulty door lock restores security and convenience—choose this unit when the original shows the symptoms described above (sticky or non-responsive locking, unusual noises from the door, or failure to lock/unlock with the central system).
