Description
An electric rear tailgate glass lock designed for Citroën C5 I and II Estate (Combi) vehicles. This direct-fit replacement part (661527) restores secure locking and reliable operation of the tailgate glass, integrating with the vehicle’s central locking system. It’s a practical spare for professional technicians and experienced DIY enthusiasts who maintain PSA Citroën/Peugeot vehicles.
Function And Benefits
The unit controls locking of the rear tailgate glass section with an electric actuator and mechanical latch. It ensures secure closure, prevents unwanted opening during driving, and communicates with the central locking system. Benefits include easy replacement, plug-and-play electrical connection on compatible models, and restored safety for cargo and passengers.
Common Faults And Causes
Failures typically result from prolonged exposure to moisture (leading to corrosion), dirt ingress, mechanical wear of the latch mechanism, electrical faults in the actuator or connectors, or freezing in cold climates. Symptoms include an inability to lock/unlock the tailgate glass, intermittent operation, unusual noises, or the central locking failing to respond for the tailgate.
Replacement And Installation Notes
- Recommended for fitment by a qualified technician or an experienced DIYer familiar with vehicle electrical systems.
- Typical replacement steps: disconnect the vehicle battery for safety; remove the interior tailgate trim panel to access the lock assembly; disconnect the electrical connector; unbolt the lock unit; fit the replacement; reconnect wiring; reassemble trim; test operation with central locking and manual actuation.
- Use basic tools (screwdrivers, Torx/hex sockets depending on vehicle trim), and check for water seals or damaged fasteners while replacing.
- After installation, verify correct locking/unlocking from the remote, interior lock switch, and manual operation to ensure full integration.
Maintenance Tips
Keep the tailgate drain channels and seals clean to reduce water ingress. Periodic lubrication of moving latch components with a suitable contact-safe lubricant can prolong service life. Inspect electrical connectors for corrosion if the vehicle is used in wet or salted-road conditions.
