How to Remove the Mirror From a Mercedes Benz 450

1. Park the car in a sunny spot. Try to park the car in an area where the internal temperature of the car reaches above 75 degrees. If you are working in the winter, you can use a small heat gun or hair dryer to warm the adhesive that holds the mirror in place. Allow the Mercedes to sit in the sun for at least two hours.
2. Locate the area where the mirror attaches to the button glued to the windshield. A small screw holds the mirror on this button. Unscrew the screw and set it aside.
3. Remove any electronic wires attached to the mirror by pulling the wires gently with pliers. These wires control the thermometer inside the mirror, the auto dim feature and sometimes a heating mechanism. Your mirror may have some or all of these features, depending on the features included on your Mercedes 450.
4. Turn the mirror gently clockwise to loosen it from the button on the windshield. Set the mirror down in a safe place where it will not get broken, scratched or sat on.
5. Grasp the sides of the button with a crescent wrench. Gently twist the button in a clockwise direction until the button pops off of the glass surface. If this does not work, insert a razor blade between the glass and the button and apply gentle pressure to pop the button off of the glass.
6. Place a small amount of adhesive remover onto any glue remaining on the surface of the glass. Allow the remover to sit for 10 minutes. Then wipe the residue away with a soft cloth. You can also use the razor blade to scrape away the adhesive.
