Description
Window regulator mechanism for the right front window of Citroën C3 first series with sequential closing function. Passenger door.
This direct-replacement power window regulator is designed for Citroën C3 first-generation passenger doors and features a sequential end-of-travel function for reliable auto-closing. Ideal for professional workshops and DIY mechanics, the unit fits original-style mounting points and is frequently searched by part numbers such as 400618 and 9222AP — useful keywords for quick lookup in catalogs and search engines.
The mechanism controls the vertical movement of the right front glass using a guided cable and motor assembly. The sequential closing function provides an automatic finish to the window travel, reducing the need to hold the switch continuously and improving user convenience. The assembly is compatible with standard door trims and electrical connectors used on the first-series Citroën C3.

Durability And Maintenance
Regular inspection of door drainage, periodic lubrication of guide rails, and prompt replacement of worn plastic parts extend service life. In workshop conditions, diagnosing noisy or slow windows early prevents motor overload and cable damage. Typical failure modes are progressive, so address unusual noises or hesitation in travel to avoid more costly repairs.
