To replace the right side mirror, you will need a small thin screw driver. Push the mirror all the way down so that you can see behind the glass. You will see a small metal wire tab. This is your retaining tab for the mirror. Lift the tab with your screw driver and the mirror will release. Install new mirror and with your screw driver pull the retaining tab up and away from the mirror to hook onto the retaining clips for the new mirror.
