Had an unfortunate incident with a board on the interstate and the mirror cover on the pass side was damaged. Have the new cover but can't find any information on how to remove the mirror to get to the cover screws inside. Looked at several utubes which show previous years are attached so the mirror is just pulled out and down to release. Doesn't want to budge and I don't wan to break the mirror. From what I can see behind the mirror it looks different from utubes so I'm thinking Lexus changed the attachment method. Any help out there?
