Fitment And Compatibility

Designed for the right/front passenger-side wiper on Citroën C4 Picasso and C4 Grand Picasso models manufactured until 2013. This unit matches common OEM mounting points and electrical connectors used on the listed vehicles. Search by OE number (for example 9687622080) is a common way technicians and DIY customers locate this part.

Installation Recommendations

• Disconnect the battery before starting work to prevent accidental activation and protect vehicle electronics.
• Mark the wiper arm position on the glass or note its resting position, then remove the wiper arm(s) to access the motor and linkage.
• Remove the cowl/plastic trim to expose the motor assembly. Keep fasteners and clips organized.
• Unplug the electrical connector and remove the motor mounting bolts. Depending on design, you may need to separate the motor from the linkage or replace the complete assembly.
• Transfer any required link arms or spacer parts to the new motor if they are not included, ensuring correct alignment before final tightening.
• Reassemble in reverse order, reconnect the battery and test the wiper park position and full sweep before refitting the cowl and wiper arm. Adjust wiper arm position if necessary.
• If unsure about disassembly of the linkage or electrical checks, have the replacement performed by a professional with appropriate tools.

Common Failure Causes

• Water ingress and corrosion leading to electrical short or seized internal components.
• Worn carbon brushes or commutator wear in the motor reducing torque or causing intermittent operation.
• Mechanical wear of gearbox gears or linkage joints producing play or complete loss of movement.
• Frozen or obstructed wiper blades that overload and accelerate motor failure.
• Corroded or damaged electrical connector and wiring causing poor contact or open circuits.

Why Replace The Wiper Motor?

A faulty wiper motor compromises driver visibility in rain and snow and must be replaced promptly. Installing a correct-fit replacement motor restores reliable operation, reduces noise and prevents uneven or incomplete wiping. For best results, inspect the entire wiper linkage and water seals when replacing the motor to avoid repeating the failure.

Additional Notes

Always use the OE/reference numbers listed above when searching for the correct part. Professional installation is recommended if access to the linkage or electrical diagnosis is required.
