Description
Window Regulator Motor – Left Front Window For Citroën C5 Vehicles From 2005–2007. Without Electric Mirror Folding Function. Driver’s Side.
This high-quality replacement power window motor is designed for the left front (driver’s side) window of Citroën C5 II models built between 2005 and 2007. Ideal for professional workshops and experienced DIY mechanics, the unit restores reliable up-and-down window operation and is commonly searched by part numbers 9649303980 and 9221AJ. The motor fits directly to the door regulator assembly and is suitable where the vehicle does not use an integrated electric mirror folding feature.
Technical Information
- Manufacturer: Stellantis (Citroën)
- Model: Citroën C5 II (2005–2007)
- Product Codes: 9649303980, 9221AJ
- Other Numbers: NFP
Function
The motor provides the drive torque to move the window glass via the door regulator mechanism. It converts electrical input from the vehicle’s window switch into rotational motion that engages the regulator gears or cable system, enabling smooth window travel and position holding.
Typical Faults And Causes
Power window motors commonly fail due to a combination of age and environmental factors: worn commutator/brushes, gear wear or plastic gear teeth breakage, cable fraying (on cable-type regulators), water ingress and corrosion inside the motor housing, or excessive load caused by seized regulator sliders or misaligned glass. Symptoms include slow movement, intermittent operation, grinding noises, or complete loss of function.
Expected Service Life
Service life depends on use and environment. In everyday conditions many motors last several years; however, units on vehicles exposed to moisture, road salt or heavy use may fail earlier. Typical failure intervals are often seen after 8–12 years or beyond 100,000 km, but this varies with maintenance and driving conditions.
Installation Recommendations
- Always disconnect the vehicle battery before starting work on door electrics to avoid short circuits and accidental operation.
- Remove the door trim and moisture barrier carefully to access the regulator and motor. Keep fixings and clips organized for reassembly.
- Before removing the motor, move the window to a position where bolts and connectors are accessible (manually or with assistance). Support the glass to prevent it dropping.
- Unplug the electrical connector and remove motor-to-regulator bolts. Inspect the regulator for worn sliders, frayed cables or damaged gears—replace the regulator if mechanically compromised.
- Fit the new motor in reverse order, secure bolts to the correct torque, reconnect the electrical connector and momentarily reconnect the battery to test operation before final reassembly.
- After installation, check window travel for smooth movement and correct sealing. Lubricate guide rails with an appropriate dry lubricant and replace any brittle clips or worn fasteners.
Why The Part Is Often Replaced
Failure usually stems from internal wear (brushes and commutator), contamination or corrosion from water ingress, or mechanical overload when the regulator is damaged or the glass is misaligned. Routine inspection of door seals and regulator components can extend motor life.
Fitment And Identification
This motor is intended for Citroën C5 II front left applications (driver’s side) from model years 2005–2007. When searching for replacements, use the OEM numbers 9649303980 and 9221AJ to locate matching units quickly.
Professional Tips
- Test the regulator movement by hand before fitting the motor to identify binding points.
- If the regulator shows visible wear or cable damage, replace the full regulator assembly together with the motor for long-term reliability.
- Perform a final function test (full up/down cycles) and check that auto-reverse or anti-pinch features (if equipped) operate correctly after reassembly.
