The part operates the window lifter mechanism and is supplied for the driver side; it also integrates with the electrically folding mirror mechanism on applicable versions.
Function And Benefits
The motor converts electrical energy into mechanical rotation to drive the window regulator, enabling smooth raising and lowering of the left front window. Benefits include straightforward replacement, restoration of proper window movement, and compatibility with factory mounting points and electrical connectors on the specified models. Including the OE references in searches increases findability: 1488726080, 1400208480, 9221V4.
Symptoms Of A Faulty Unit
Common symptoms indicating a failing motor: slow or jerky window movement, window stuck in one position, grinding or unusual noises inside the door, or complete loss of window operation on the driver side. Intermittent function can also point to worn brushes or electrical contact issues within the motor.
How To Replace
Replacement is suitable for experienced automechanics and competent DIYers. Typical replacement steps:
- Disconnect the negative battery terminal to prevent short circuits and accidental activation.
- Remove the door trim panel and vapor barrier carefully to access the regulator and motor.
- Disconnect the electrical connector from the motor and detach any retaining clips or bolts.
- Unbolt the motor from the regulator assembly. If the motor is integrated with the regulator, remove the whole regulator.
- Install the new motor (or regulator), secure all fasteners to manufacturer torque values, reconnect the electrical connector and test operation before refitting the door panel.
- Reassemble door trim and confirm full window travel, auto functions and mirror folding if applicable.
Technical Information

Installation Recommendations
- Perform installation on a stable workbench or hoisted vehicle with the door open and secure.
- Always disconnect the vehicle battery before removing or fitting the motor to avoid electrical damage.
- Inspect window regulator tracks, cables and mounting points when replacing the motor; worn regulator components shorten motor life and should be replaced together if necessary.
- Use appropriate tools and follow manufacturer torque specifications for fasteners to ensure correct alignment and operation.
- After installation, cycle the window several times to check for smooth operation and correct limit positions.
Why The Part Fails Most Often
Failure usually results from normal wear of internal components such as brushes, commutator wear, or gear degradation from frequent use. Water ingress or corrosion inside the door, obstructed regulator tracks, and stretched or frayed cables can increase load on the motor and accelerate failure. Electrical issues like poor connector contact or blown fuses may mimic motor faults but should be checked during diagnosis.
Suitable For Professionals And DIY: This motor is aimed at professional mechanics and car owners who perform their own repairs. Including OE numbers in listings helps workshops and customers locate the correct part quickly for Citroën C8 and Peugeot 807 repairs.
