How do you change an electric wing mirror on a Citroen C3?

To change an electric wing mirror on a Citroen C3, first, disconnect the vehicle's battery for safety. Remove any plastic covers and unscrew the mirror assembly from the door by taking out the screws or clips holding it in place. Disconnect the wiring harness from the back of the mirror, then replace it with the new mirror by reconnecting the harness and securing it with screws. Finally, reattach any covers and reconnect the battery before testing the new mirror.
