How do you Replace wing mirror on a Renault scenic?

Remove the mirror glass by prying it out gently from the top of the housing. Use a flat, thin tool to do this and be careful. Release the four clips behind the glass and this will remove the outer shell. Open the door and look for the mounting screw on that side, it will be covered while the door is closed. Remove that screw. Close the door and fold the mirror in, there will be another screw that connects the hinge to the car. Remove this screw and the whole piece will be free. Repeat the steps backwards with the new mirror for installation.
