Description
Electric window regulator mechanism for the left front driver’s window for Citroën C1 and Peugeot 107 up to 2013.
This electric window regulator is a direct-fit replacement designed for the left front (driver’s) door of Citroën C1 and Peugeot 107 models produced up to 2013. Ideal for professional workshops and experienced DIYers, the unit restores smooth, reliable window movement, reduces rattles and grinding noises, and helps maintain door sealing. Many customers search by part numbers, so this listing includes the common codes (e.g. 9221T8, 1629054280) for faster identification.
Function
The regulator converts the rotation of the electric motor into linear movement that raises and lowers the window glass. It secures and guides the glass within the door, keeping it aligned with the seals to prevent wind noise and water ingress. In this application the mechanism is built for the left front (driver’s) door and is intended to work with the original motor and electrical connector configuration of Citroën C1 / Peugeot 107.

Installation Recommendations
Basic professional procedure (high-level):
- Disconnect the battery before starting work to avoid short circuits and accidental motor operation.
- Remove the inner door trim and protective moisture barrier to access the regulator and motor.
- Support the window glass in a safe position (tape or suction device) and, if necessary, loosen the glass mounting bolts to separate it from the old regulator.
- Disconnect the electrical connector, unbolt the regulator and motor assembly, and remove the old part from the door.
- Install the replacement regulator, reconnect the glass to the regulator, and temporarily reconnect power to test smooth travel and correct alignment before reassembling the door.
- Re-fit the moisture barrier and door trim. Check final operation at least 5–10 cycles to ensure quiet, consistent movement.
Use appropriate tools, replace any damaged clips or foam, and apply light lubricant to sliding tracks where recommended. Verify that the glass runs true in the guides to avoid premature wear.
Why It Fails Most Often
- Motor Wear: Repeated use causes the electric motor to weaken or fail over time.
- Cable Or Gear Damage: Cables can fray and snap or plastic gears can strip, leading to slipping or no movement.
- Corrosion And Water Ingress: Moisture entering the door accelerates corrosion of moving parts and electrical contacts.
- Seized Guides: Dirt and lack of lubrication cause guides and sliders to bind, increasing load on the motor.
- Impact Or Misalignment: Door impacts or improper previous repairs can bend tracks or stress the regulator, causing premature failure.
Common symptoms include slow or intermittent movement, grinding or clicking noises, the window falling down, or complete lack of response from the switch.
