Description
Electric window motor – front left window for Citroën C5 vehicles from 2005–2007. Without electric mirror folding function. Driver’s side.
Replacement electric motor for the front left (driver side) window of Citroën C5 II models produced between 2005 and 2007. This motor drives the window regulator to raise and lower the glass and is commonly searched by part numbers 9649303980 and 9221AJ. Intended for use in vehicles without the electric mirror folding feature, the unit is suitable for professional workshops and experienced DIY mechanics who perform door repairs and window mechanism replacements.
Technical Information
- Manufacturer: Stellantis (Citroën/Peugeot)
- Model: Citroën C5 II (2005–2007) — Front Left / Driver Side
- Product Codes: 9649303980, 9221AJ
- Other Numbers: NFP
Function
The motor converts electrical input into rotary motion to operate the window regulator mechanism, allowing the door glass to move up and down. It works together with the regulator assembly, door switches, and vehicle wiring to provide smooth window operation.
How To Replace (Overview)
- Disconnect the battery before starting work to avoid short circuits and accidental activation.
- Remove the interior door trim and protective moisture barrier to access the regulator and motor.
- Support or remove the glass from the regulator (secure it to prevent falling).
- Disconnect the motor electrical connector and unbolt the motor from the regulator assembly.
- Install the new motor in reverse order—tighten fasteners, reconnect the connector and carefully test window movement before refitting the door trim.
- Check regulator alignment and lubricate guide rails if necessary. Reconnect the battery only after reassembly is sufficiently secured.
Installation Recommendations
- Always disconnect the battery prior to removal and follow manufacturer guidelines to avoid damage.
- Inspect the regulator, guide rails, and glass clips while the door is open; replace worn components to prevent repeat failure.
- Test the motor and regulator operation before reinstalling the door trim to ensure correct fitment and alignment.
- Use appropriate hand tools and avoid forcing the mechanism; if the regulator is seized, free the glass and mechanism manually before applying power.
Most Common Causes Of Failure
- Water ingress and corrosion damaging electrical contacts or internal gears.
- Worn motor brushes or commutator leading to reduced torque or intermittent operation.
- Broken or stripped plastic gear teeth inside the motor or regulator assembly.
- Frayed or detached regulator cables and worn guide rails causing excess load on the motor.
- Debris in the window track or lack of lubrication increasing friction and motor strain.
Fitment Notes
Fits Citroën C5 II models from 2005 to 2007 for the front left (driver) door on vehicles without electric mirror folding. Always verify the part numbers 9649303980 and 9221AJ against the existing unit when possible to ensure correct fitment.
For technicians: This part is commonly ordered by its product codes (9649303980, 9221AJ). Thorough inspection of the regulator and door mechanics during replacement reduces the chance of early re-failure.
