Technical Information
- Manufacturer: Stellantis / Citroën
- Model: Citroën C4 (First Generation) – Front Left / Driver’s Door
- Product Codes: 9681576080, 9221AY
- Additional Numbers: 9222AY
Function
The unit houses an electric motor that drives the window regulator mechanism, converting electrical input into rotary motion to raise and lower the door glass. It works together with the regulator gears, cables or scissor mechanism (depending on the regulator type) and the door switch to provide controllable and safe window movement.
Replacement Procedure
- Disconnect Battery: Always disconnect the negative terminal of the battery before starting work to avoid short circuits or accidental activation.
- Remove Door Trim: Carefully remove the inner door panel and any weather seals to gain access to the regulator and motor assembly.
- Support Glass: Secure the window glass in the closed position or support it with tape/clamps before detaching the motor/regulator mounting points.
- Disconnect Electrical Connector: Unplug the motor connector and remove any retaining clips or screws holding the motor to the regulator.
- Remove Motor: Detach the motor from the regulator assembly. If replacing only the motor, separate it from the regulator; if exchanging the complete regulator, remove the whole assembly as required.
- Install New Motor: Fit the new motor, reconnect the electrical connector and test the window operation before reassembling the door trim.
- Final Check: Verify smooth travel over full range, no binding, and that switches operate correctly. Refit trim and reconnect the battery.
Installation Recommendations
- Use Correct Tools: Use panel trim tools to avoid damaging clips and door trim. Use correct torque for fasteners where applicable.
- Lubrication: Lightly grease regulator tracks and sliding points with appropriate lubricant to reduce wear and noise.
- Alignment: Ensure glass is correctly seated in the regulator before tightening all fasteners to prevent binding or uneven wear.
- Electrical Checks: Inspect connector pins for corrosion and wiring for damage; clean contacts if needed before connection.
- Test Before Reassembly: Always test full operation of the window before fitting the door card to confirm correct installation.
Common Failure Causes
- Mechanical Wear: Worn brushes, gears or regulator components lead to reduced torque, noise or complete failure over time.
- Water Ingress: Moisture entering the door can corrode motor internals or connectors, causing intermittent or permanent faults.
- Overload/Obstruction: Forcing the window against an obstruction can damage motor gears or the regulator mechanism.
- Electrical Issues: Corroded connectors, broken wires or faulty switches can mimic motor failure; always check wiring before replacing the motor.
