How do you replace a drivers side mirror on a Saturn SL1?

Take the panel off that's inside the door, not the door panel just the little one right even with the mirror. There are then three 10 mm nuts holding it on.

After seeing how the mirror was assembled on the internet, it was obvious that I had to take off the little cover, but I didn't know what washeld it on either. It is held on by an expansion snap, so gently pry it off with your fingers and you won't break it. Then you have the access to the screws holding on the mirror. After replacing the mirror it will snap back into place.
