Technical Information

• Manufacturer: Stellantis (Citroën/Peugeot)
• Model: Citroën C5 II (2005–2007)
• Product Codes: 9681597380, 9221AK
• Other Numbers: 985173-100

Compatibility And Application

Primarily intended for Citroën C5 second generation vehicles produced between 2005 and 2007. Matches common PSA/Stellantis OEM references used on left front door assemblies. Searching by product codes 9681597380 or 9221AK helps quickly locate the correct unit.

Function

The motor drives the window regulator mechanism to raise and lower the door glass. It converts electrical input from the window switch into rotational motion that moves the regulator gears or cable system. In some vehicle configurations the unit works in conjunction with mirror folding features and door electronics.

How To Replace

• Disconnect Negative Battery Terminal To Prevent Short Circuits.
• Remove Inner Door Trim Carefully, Taking Out Screws And Clips Without Damaging Retainers.
• Peel Back Vapor Barrier And Support The Glass (use suction cup or tape) To Prevent Dropping.
• Disconnect Electrical Connector From Motor, Then Unscrew Motor Mounting Bolts.
• Detach Motor From Regulator (or Remove Regulator Assembly If Required) And Replace With New Unit.
• Reconnect Wiring, Test Window Operation Before Reassembling Door Trim, Then Refit Vapor Barrier And Trim Panel.

Installation Recommendations

• Perform A Functional Test Of The New Motor Before Refitting The Door Trim To Save Time If Adjustment Is Needed.
• Use A Non-Corrosive Electrical Contact Cleaner On Connectors And Apply A Small Amount Of Dielectric Grease To Prevent Moisture Ingress.
• Support The Glass Securely During Work To Avoid Chipping Or Breakage.
• Check Regulator Condition At The Same Time; Replace Worn Regulator Components To Prevent Premature Motor Failure.

Most Common Failure Reasons

• Wear Of Carbon Brushes And Commutator Due To Long Service Life.
• Water Ingress And Corrosion From Damaged Door Seals Or Vapor Barrier.
• Mechanical Overload Caused By Damaged Regulator Gears Or Misaligned Window Glass.
• Electrical Issues Such As Short Circuits Or Intermittent Wiring Causing Motor Overheating.

Replacing the motor and addressing any underlying regulator or sealing issues will restore smooth, quiet window operation and reduce the chance of repeat failures. Use the listed product codes (9681597380, 9221AK, 985173-100) when searching to ensure the correct match for Citroën C5 II left front applications.

Restore reliable window operation and the electric mirror folding function with this direct-fit window regulator motor for the left front (driver’s) side. Designed for workshops and DIY mechanics, the unit replaces failed or weak motors to eliminate slow, noisy or non-functioning window travel. The motor is suitable for vehicles where the electric mirror folding feature is integrated into the same control module.

Technical Information

Application And Compatibility

Direct replacement for the left front (driver) door of Citroën C5 second generation models manufactured between 2005 and 2007. Intended for vehicles that use the listed part numbers. Fits vehicles with combined power window motor and electric mirror folding control.

Function And Typical Symptoms

The motor drives the window regulator mechanism to raise and lower the left front window and integrates the control for the electric folding mirror. Common symptoms of a failing unit include slow or intermittent window movement, complete loss of window function at the driver side, unusual grinding or buzzing noises during operation, and failure of the mirror folding feature when the mirror command is activated.

Most Common Failure Causes

• Mechanical wear of internal gears and regulator linkages caused by long service life and repeated use.
• Water ingress and corrosion inside the motor or connector leading to electrical faults or seized components.
• Worn motor brushes or armature deterioration resulting in reduced torque and intermittent operation.
• Damaged wiring, poor terminal contacts, or faulty switches causing loss of power to the motor.
• Overload from a jammed window or bent regulator that increases stress on the motor and accelerates failure.

Installation Recommendations

• Tools Required: Trim removal tools, Torx and Phillips screwdrivers, socket set, pliers, and a non-marring support for the glass.
• Safety: Disconnect the negative battery terminal before starting work to avoid short circuits or accidental window movement.
• Procedure Overview: Remove interior door trim and moisture barrier carefully; support the glass in its position; detach the window from the regulator; unbolt and disconnect the motor electrical connector; install replacement motor, reconnect wiring and test operation before reassembling the door.
• Testing: Cycle the window several times and verify mirror folding function after installation to ensure correct operation and that the regulator moves freely.
• Tips: Keep fasteners and clips organized, replace any damaged vapor barrier to prevent future moisture ingress, and lubricate regulator pivot points with a suitable grease for smooth operation.

Why Replace This Part

Replacing the motor resolves loss of window function and restores convenience and safety for the driver. A properly functioning motor prevents water ingress into the door cavity caused by gaps when the window cannot fully close and avoids further damage to the regulator and associated electrical components.

For Whom This Part Is Intended

Designed for professional mechanics and competent DIY enthusiasts familiar with door trim removal and basic electrical disconnection. Suitable when the listed product codes match the vehicle’s requirements.
