How do you change a wing mirror control on a citron Picasso?

To change the wing mirror control on a Citroën Picasso, first, ensure the vehicle is turned off and the keys are removed. Use a flathead screwdriver to carefully pry off the control panel covering the mirror switch, taking care not to damage it. Disconnect the wiring harness from the old switch and replace it with the new one, then reassemble the panel by snapping it back into place. Finally, test the new control to ensure it functions correctly.
