This motor restores smooth, quiet window operation and is often searched for by part numbers 9647441880 and 9221AY — include these codes when ordering to ensure correct fitment.
Benefits
Robust 12V electric drive engineered to meet the load and travel patterns of OE window systems. Helps eliminate slow, noisy or non-functioning windows caused by worn motors or seized gears. Direct replacement for the left front door with straightforward installation, reducing workshop downtime.
Technical Information
- Manufacturer: Stellantis (Citroën/Peugeot)
- Model: Citroën C4 (First Generation) – Left Front / Driver’s Door
- Product Codes: 9647441880, 9221AY
- Additional Numbers: 9221.AY (alternate format)
- Type: Electric Window Motor (12 V DC)
- Location: Left Front (Driver’s Door)
How It Works
The motor drives the window regulator assembly to raise and lower the glass. It converts 12V DC electrical input into rotational motion, which is transmitted through gears or a cable mechanism to move the window. Proper function depends on both the motor and the regulator tracks being free of corrosion and debris.
Common Failure Causes
- Water ingress and corrosion of gears or motor brushes, especially on older doors with degraded seals.
- Wear of internal brushes or bearings leading to reduced torque and intermittent operation.
- Mechanical binding of the regulator (bent tracks, frayed cables) causing overload and motor burnout.
- Electrical issues such as poor connector contacts or damaged wiring.
Installation Recommendations
Recommended For: Professional mechanics and competent DIYers. Typical replacement time depends on experience: allow approximately 1–2 hours.
- Always Disconnect Battery Before Starting Work To Avoid Short Circuits And Prevent Damage.
- Remove Interior Door Trim Carefully To Preserve Clips And Fasteners.
- Support The Glass Securely Before Removing The Motor/Regulator Fasteners (Use Suction Cups Or Tape To Hold The Glass In Position).
- Note The Regulator And Glass Position Before Removal To Ensure Correct Reassembly And Alignment.
- Disconnect The Electrical Connector And Unbolt The Motor From The Regulator; Transfer Any Required Brackets Or Spacers From The Old Unit.
- After Installing The New Motor, Reconnect The Battery And Test Full Window Travel Before Reassembling Door Trim.
- Lubricate Regulator Tracks And Check For Smooth Operation; Replace Regulator Components If Binding Is Present.
Why Replace Rather Than Repair
In many cases the motor is the simplest and most cost-effective component to replace when windows operate slowly, make grinding noises, or stop moving. If mechanical damage to the regulator is evident, replace or repair the regulator assembly at the same time to prevent premature failure of the new motor.
Compatibility And Ordering Tip
Search using OE numbers 9647441880 or 9221AY to find the correct match. This part is intended for the left front (driver’s) door of Citroën C4 first-generation models. When replacing, verify physical match to the original unit (mounting points, connector type, and pinout) before final installation.
Notes For Professionals
When fitting in a workshop environment, inspect the door for signs of water ingress and damaged seals. Replace worn regulators, damaged clips or corroded connectors to ensure long-term reliability. After installation, perform several full up/down cycles to confirm smooth operation and proper seating of glass in its run channels.
