Description
Window regulator motor for the left front window for Citroën C8 and Peugeot 807. Electrically folding mirror. Driver’s side.
This electric window regulator motor is a direct-fit replacement for the left front (driver’s side) window on Citroën C8 and Peugeot 807 models. Supplied with OEM cross-reference numbers 1488726080, 1400208480 and 9221V4, it restores reliable up/down operation and smooth window travel. Ideal for professional workshops and competent DIY mechanics, the unit is designed to meet the original specifications of Stellantis passenger vehicles and to reinstall quickly when the regulator or motor fails.
Technical Information
- Manufacturer: Stellantis / Citroën / Peugeot
- Model: Citroën C8, Peugeot 807
- Product Codes: 1488726080, 1400208480, 9221V4
- Additional Numbers: 9221V4 (cross-reference)
Function And Benefits
The unit is a 12V DC electric motor assembled with the window regulator interface to move the glass up and down. Replacing a worn motor restores smooth, quiet operation, prevents glass misalignment and reduces load on the regulator mechanism. Using the correct OEM-referenced motor helps avoid electrical issues and repeated failures.
Fitment And Compatibility
Fits Left Front (Driver’s Side) of Citroën C8 and Peugeot 807. The part is commonly searched and identified by the OEM numbers listed above—entering these codes in parts catalogues or search fields increases the chance of a correct match.
Installation Recommendations
- Disconnect the vehicle battery before starting to avoid short circuits and prevent accidental motor operation.
- Remove the interior door trim and detach any speakers or trim clips to access the regulator assembly. Take care with the moisture barrier.
- Secure the glass in the up position using tape or a wedge to prevent it from falling when the regulator is removed.
- Lower the window to access the fixing bolts that join the glass to the regulator. Support the glass while undoing the bolts.
- Disconnect the electrical connector to the motor and unfasten the motor/regulator mounting bolts. Remove the motor from the regulator assembly.
- Fit the replacement motor, connect the electrical plug and test the window operation (up and down) before reassembling the door panel.
- Lubricate regulator tracks and pivot points with an appropriate grease, check that the glass runs true, then reattach the moisture barrier and door trim.
- If the window still operates slowly or intermittently, inspect switches, fuses and wiring for voltage drops or corrosion.
Most Common Reasons For Failure
- Wear Of Internal Motor Brushes Or Gears — Over time carbon brushes and small gear teeth degrade, reducing torque.
- Corrosion And Water Ingress — Door seals or blocked drains allow moisture into the mechanism, causing rust and electrical faults.
- Regulator Cable Or Plastic Component Failure — Plastic sliders and cables can fray or break, jamming the system and overloading the motor.
- Excessive Load Or Jamming — Misaligned glass or foreign objects in the track increase load and accelerate motor wear.
- Electrical Issues — Faulty switches, relays or poor connectors lead to intermittent operation or reduced voltage to the motor.
Typical Service Life: Varies by use and environment; many window motors function reliably for 8–15 years, but aggressive use, salt and moisture exposure shorten this lifespan. Replacing a failing motor promptly prevents damage to the regulator and glass.
Note: The original description referenced an “Electrically folding mirror.” The primary function of this product is the left front window regulator motor; it is intended to operate the door glass, not to act as a mirror folding actuator.
