Description
Driver’s window switch for Citroën C4 Picasso and Grand Picasso first generation. With mirror folding function for the vehicle. Original fully functional used part. May show signs of wear.
This genuine used driver’s master window switch (Part Numbers: 96639383ZD / 6554YH) is a practical replacement for first generation Citroën C4 Picasso and Grand C4 Picasso models. Designed for mechanics and DIY enthusiasts, the unit restores convenient power window operation and the mirror folding function. The switch is a direct-fit electrical component and is ideal when the original switch shows intermittent operation, sticky buttons, or damaged plastic surrounds.
Function And Application
The switch is the driver-side master control for power windows and includes the electric mirror folding function. In typical configurations it controls the driver window directly and provides commands to the other window motors and mirror fold actuator via the vehicle’s wiring harness. Replacing a faulty master switch will often restore smooth window travel, proper one-touch operation (if originally fitted), and reliable mirror folding.

Installation
- Tools Needed: Trim removal tools, small ratchet or screwdriver set (Torx/Phillips depending on vehicle), gloves.
- Procedure Overview: Carefully remove the door trim panel and/or armrest bezel to access the switch. Unscrew any fasteners holding the switch module, depress the retaining clips and unplug the electrical connector. Install the replacement switch by reversing the steps, reconnect the connector and refit the trim.
- Testing: Before fully reassembling the door card, reconnect the battery if disconnected and test all window functions and mirror folding to confirm correct operation.
- Safety Note: Disconnect the negative battery terminal before starting work on vehicle electrics to reduce risk of short circuits. Use plastic trim tools to avoid breaking clips or scratching interior panels.
Mounting Recommendations
- Inspect Wiring And Connectors: Clean the connector contacts with appropriate contact cleaner and ensure pins are straight and corrosion-free.
- Seat The Connector Fully: A partially connected plug can cause intermittent faults. Make sure the locking tab engages.
- Protect Trim Clips: Work methodically when removing and refitting door panels; lining up clips and fasteners prevents rattles and damage.
- Final Check: Test window up/down travel, child lock functions (if equipped), mirror folding and any one-touch operation before final assembly.
Why This Part Most Often Fails
Common causes of failure include wear of internal electrical contacts due to frequent use, dirt or moisture ingress leading to corrosion, cracked solder joints on the switch PCB, and broken plastic actuators or mounting clips. Spills inside the door or persistent condensation can accelerate contact degradation. In many cases, symptoms are intermittent operation, stuck buttons, or complete loss of a window or mirror fold command.
