How do you replace a door mirror on a citroen c5?

To replace a door mirror on a Citroën C5, first, ensure the vehicle is turned off and the keys are removed. Carefully pry off the mirror's plastic cover to access the mounting screws, then unscrew and disconnect the electrical connector if the mirror is powered. Remove the old mirror and replace it with the new one, reconnecting the electrical connector and securing it with screws. Finally, snap the plastic cover back into place and test the mirror for proper function.
