Description
Passenger window switch for Citroën C4 Picasso and Grand C4 Picasso first generation. May show signs of use.
High-quality replacement passenger power window switch designed for first-generation Citroën C4 Picasso and Grand C4 Picasso. Ideal for professional workshops and DIY mechanics who need a reliable, direct-fit control unit to restore smooth window operation. The switch is commonly searched by its product codes, so use the reference numbers below when ordering or searching online to find the correct part quickly.
Function and Fitment
This part controls the passenger-side electric window motor and the relevant safety features (anti-pinch behavior is controlled by the vehicle body electronics). It is intended as a direct replacement for the original door switch module on Citroën C4 Picasso I and Grand C4 Picasso I models. After installation, test the switch for full travel in both directions and verify that the window registers limit positions correctly.
How To Replace
Replacement is straightforward for experienced technicians and competent DIYers:
- Disconnect the negative battery terminal before starting work to avoid short circuits and to protect vehicle electronics.
- Remove the door trim panel and any retaining clips or screws (plastic trim tools recommended to avoid damage).
- Unscrew or unclip the switch bezel and carefully release the window switch module from the door panel.
- Unplug the electrical connector and fit the new switch in reverse order.
- Reconnect the battery and test the switch operation (open/close and any memory/auto functions) before reassembling the door trim.

Installation Recommendations
Use correct trim removal tools to prevent damage to door panels. Keep mounting screws and clips organized during disassembly. After installation, always confirm electrical connectors are fully seated and that the window moves freely in the guide—binding or obstructions will overload the new switch. If the vehicle exhibits any unusual electrical behavior after fitting, inspect fuses and wiring for damage before proceeding.
Why This Part Most Often Fails
Common failure causes include mechanical wear of the internal contacts from frequent use, contamination by moisture or dirt, corrosion of connector pins, and plastic actuator breakage. Intermittent operation or complete loss of function is typically caused by worn contact surfaces or a faulty connector rather than the window motor itself.
