Replacing a mirror

I have a 2006 Ford Focus and need to replace the drivers side mirror. However I need some help installing it. Does anyone know how?

remove the interior trim panel, be careful. now r&i the mirror

The few that I’ve replaced have been installed thusly. An interior trim piece in the corner of the door frame pops out and there are three nuts behind it. Remove those nuts and the mirror assembly pulls straight out, the plug for power mirrors being behond the mirror assembly.

In some vehicles the inner door panel needs to be removed to access the lower screw(s).
