Compatibility

Designed for use on Citroën C8 and Peugeot 807 models, left front (driver) side. Always compare product codes to your existing part before ordering.

How Replacement Is Performed

Replacement typically requires removal of the inner door trim to access the regulator and motor assembly. Steps generally include:

• Disconnecting the negative battery terminal before starting work to prevent short circuits.
• Removing door trim panel, vapor barrier and any clips or screws securing the door card.
• Disconnecting the wiring connector from the motor and unbolting the motor and regulator from the door shell.
• Removing the old motor from the regulator (or the complete regulator assembly if replacement is needed) and fitting the new motor in the correct orientation.
• Reassembling components, reconnecting the battery and testing window operation before final door trim refit.

Installation Recommendations

• Always Disconnect The Battery Before Removing The Door Panel To Avoid Electrical Damage.
• Inspect The Regulator Tracks, Cables And Mounting Points For Wear Or Damage — Replace The Entire Regulator If The Mechanism Is Severely Worn.
• Lubricate Sliding Tracks With Appropriate Grease To Reduce Friction And Extend Service Life.
• Test Window Operation Several Times After Installation To Ensure Smooth Travel And Correct Alignment Before Final Reassembly.

Why This Part Commonly Fails

Window motors and regulator assemblies are subject to mechanical wear and environmental factors. Common causes of failure include worn brushes or gears inside the motor, corrosion from moisture ingress, seized regulator rollers or cables, and strain from misaligned windows. Frequent use, exposure to water and dirt, or a failing regulator mechanism will accelerate motor wear.

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

• Manufacturer: Stellantis
• Model: Citroën C8; Peugeot 807
• Product Codes: 1488726080, 1400208480, 9221V4
• Other Numbers: 9221V4

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.
