Key Features
- Driver’s master window switch with integrated mirror folding control.
- Original equipment (OEM) part from the Stellantis family (Citroën/Peugeot).
- Plug‑and‑play replacement for compatible first‑generation C4 Picasso vehicles (physical fitment required).
- Used but fully functional; may show cosmetic signs of use.
Function
The switch controls the driver’s window and provides the mirror folding command for the vehicle. As the master switch assembly on the driver’s door, it commonly houses controls for other windows and mirror adjustment depending on vehicle specification. Replacing a faulty switch restores normal electric window operation and the convenience of folding mirrors from the driver’s position.
Installation
Basic replacement steps for a typical door installation (worksop level / experienced DIY):
- Disconnect the battery before starting work to avoid short circuits and accidental activation.
- Remove the door trim panel using appropriate plastic trim tools to prevent damage.
- Unscrew and free the switch module from the door armrest/trim (retain screws and clips).
- Unplug the electrical connector(s) and carefully remove the old switch.
- Fit the replacement switch, connect the wiring harness and test functions (windows, mirror folding, locking if applicable) before reassembling the door panel.
- Reinstall the door trim and reconnect the battery. Verify full functionality after installation.

Why This Part Fails
Common causes of failure for window switches include:
- Wear of internal contacts from frequent use, leading to intermittent operation or total failure.
- Water or moisture ingress from leaks or open windows, causing corrosion of contacts or short circuits.
- Dirt and debris accumulation inside the switch mechanism impairing contact movement.
- Mechanical damage to plastic actuators or mounting tabs from impact or rough removal.
