The side view mirrors on a car are delicate, and it doesn't take much to damage one. Professional auto repair shops might charge an arm and a leg to fix a broken mirror, but luckily ,it isn't hard to repair a car mirror on your own. With the proper tools, you can replace the glass in a few minutes and be on your way, and for much cheaper than you would have paid at the dealership.
Purchase a new mirror designed for your car. There are a number of websites that offer a selection of car mirrors, such as DiscountAutoMirrors.com. You can also pick one up from a local junkyard or auto glass shop.
Use a flat tip screwdriver and a hairdryer, applying heat to the rest of the broken mirror in the frame then prying out the remaining shards. Make sure to scrape off all the glue and broken glass that you can, and use a vacuum cleaner to suck up any broken glass as you go.
Clean the frame and the new mirror with water. Wipe them down and allow them to dry briefly before applying the adhesive.
Squeeze a quarter-size amount of silicone adhesive into the centre of the frame and smear it outward towards the four corners. Avoid spreading the adhesive beyond the edge of the frame.
Tape the mirror securely to the frame with painter's tape then wait 24 hours before driving the vehicle.
If your mirror has a heating element behind the glass, use a razor to peel it away from the broken mirror before applying heat to the adhesive with the hairdryer. When you put the new mirror on, simply use silicone adhesive and reattach the element to the back of the mirror.
