Description
Right front wiper motor for Citroën C4 Picasso and C4 Grand Picasso. Passenger side. Up to 2013.
Product Overview
This replacement right front wiper motor (passenger side) is suitable for Citroën C4 Picasso and C4 Grand Picasso models built up to 2013. Ideal for workshops and DIY mechanics who search by part number (e.g. 9687622080, 6405NG), the unit restores reliable windscreen wiping performance when the original motor shows signs of wear or electrical failure.
Why Replace This Part
Wiper motors are a critical safety component, ensuring clear visibility in rain and snow. Common symptoms indicating a failing motor include slow or intermittent wiper movement, wobbling or stuck wipers, unusual grinding or clicking noises from the wiper area, or complete loss of function on the passenger-side arm. Replacing a faulty motor returns proper sweep speed and torque, preventing further damage to the wiper linkage and arms.

Compatibility Notes
Fits right front (passenger side) on C4 Picasso and C4 Grand Picasso models manufactured until 2013. Always check the part numbers listed above when searching for compatibility to ensure a direct fit replacement.
Installation Recommendations
- Disconnect the battery before starting any work on the electrical system to avoid short circuits and unintended motor operation.
- Remove the wiper arm (mark its park position), then remove the cowl/plenum cover to access the motor and linkage.
- Unplug the electrical connector and unbolt the motor from its bracket. Inspect the linkage for wear or seized joints — in many cases the linkage is transferred to the new motor.
- Fit the motor, secure fasteners to the manufacturer’s torque settings, reconnect the electrical connector and reassemble the cowl and wiper arm in the original park position.
- After installation, reconnect the battery and perform a functional test through a full wipe cycle to confirm correct sweep, park position and absence of abnormal noises.
Most Common Failure Causes
- Water Ingress And Corrosion: Seal failure or blocked drain paths allow moisture to reach the motor and reduce electrical contacts or corrode internal gears.
- Mechanical Wear: Brushes, commutator or internal gears wear over time, reducing torque and causing intermittent operation.
- Seized Or Damaged Linkage: Excessive play or seized joints in the wiper transmission increase load on the motor and accelerate failure.
- Electrical Issues: Poor connectors, damaged wiring or blown fuses in the circuit can mimic motor failures; always verify supply and grounds before replacement.
Practical Tips For Workshops
- When replacing the motor, inspect and lubricate the linkage pivots and check the condition of wiper arms and blades — uneven blades can overload the motor.
- Keep record of the part numbers (9687622080, 6405NG, 6405PG, 6405KS, 6405PH) in the job sheet to speed future servicing and warranty tracking.
