Federal code mandates that all vehicles manufactured nowadays compass a rearview mirror provided the vehicle is equipped with a rear window. But, since the mirror is essentially glued onto the windscreen it is somewhat banal for the mirror to fall off. Whether this happens you duty to either reinstall it or install a modern rearview mirror. If you choose to drive the vehicle without one, you risk being fined if pulled over in a traffic stop and you risk failing a state vehicle inspection.
Wipe the windshield clean with an alcohol rub.3. Coat the back of the rearview mirror button with rearview mirror adhesive. This adhesive is readily available at most auto part stores.
Instructions
1. Scrape the old glue off the inside of the windshield with a small metal scraper or flat razor blade.2.4. Press the button onto the windshield and hold it in place for one minute while the glue becomes tacky. Let go of the button but wait one hour before attaching the mirror to the button.
5. Place the base of the rearview mirror onto the windshield, directly above the button and then slide the mirror onto the button.
6. Tighten the set-screw located on the base of the mirror. This secures the mirror to the button. Usually, the set-screw requires an Allen wrench for tightening.
