Description
Right Front Window Regulator Mechanism For CITROËN C4 5-Door First Series – Front Passenger Door
Product Overview
This right front window regulator mechanism is designed for the front passenger door of the Citroën C4 5‑door (first series). It restores reliable up-and-down movement of the window and is a common spare part for workshops and DIY mechanics servicing Citroën C4 vehicles. Often searched by part numbers such as 9657133580, 1629054680 or 9222V0, this unit is an essential repair item when the door glass no longer operates smoothly or becomes stuck.
Function
The window regulator mechanism converts the rotary motion of the window motor (or manual crank) into linear motion to raise and lower the glass. It keeps the glass aligned in the door track and transfers load through cables, sliders and guide rails. When functioning correctly, it provides quiet, smooth movement and secure positioning at any height.
Replacement Procedure
- Disconnect Battery: For safety, disconnect the negative battery terminal before starting electrical work.
- Remove Door Trim: Carefully remove interior door card and any trims to access the regulator and motor assembly.
- Secure Glass: Lower the window to a position where you can access the glass clamps, then secure the glass to prevent dropping.
- Disconnect Wiring: Unplug the window motor connector and remove any switch wiring as needed.
- Remove Regulator: Undo the retaining bolts and detach the regulator from the door and glass. Pay attention to the position of guides and clips.
- Install New Unit: Fit the new regulator in the same orientation, secure bolts, reattach the glass and reconnect wiring.
- Test Operation: Reconnect the battery and test the window travel and alignment before reassembling the door card.
- Reassemble: Once correct operation is confirmed, refit the door trim and finalise fasteners.

Why This Part Fails Most Often
Window regulators typically fail due to worn cables, frayed or broken plastic sliders, seized rollers, or corrosion from moisture ingress inside the door. Repeated use, overload (forcing the window), and mechanical impact (door damage) accelerate wear. Symptoms include slow movement, unusual noise, irregular travel, or the glass falling out of position.
