How do you change a C3 Picasso wing mirror?

To change a C3 Picasso wing mirror, first, ensure the vehicle is turned off and parked safely. Use a flathead screwdriver to carefully pry off the plastic cover on the interior door panel, then remove the screws or clips securing the panel. Disconnect the wiring harness from the old mirror, unscrew the mirror from the door, and replace it with the new mirror. Reconnect the wiring, reattach the door panel, and finally, test the new mirror for proper operation.
