How to Fix a Loose Rearview Mirror?
2 Answers
First, remove the rearview mirror, apply glue to the loose area, reinstall the mirror, and check if it is stable. If it remains unstable, repeat the removal and installation process. Adjust the tightness of the screws to set the rearview mirror at an appropriate level. Screw location: Look up from the bottom of the exterior rearview mirror to find a hole about the size of a thumb.
Last time when I got my car repaired, the mechanic taught me that loose rearview mirrors should be handled based on different situations. For manually adjustable ones, it's usually the base fixing screw that's loose. Just use a suitable hex key to reach in from the bottom of the mirror and tighten it, but remember to hold the mirror base steady with your hand first. If it's an electric rearview mirror that's loose, it might be due to wear on the internal adjustment motor's clip or deformation of the mounting bracket. In this case, you'll need to remove the door panel to fix it. If you're doing it yourself, first disconnect the door fuse to prevent short circuits, and be careful when prying off the mirror glass to avoid pulling off the heating wires. If the entire rearview mirror is wobbling, the base welding points might have come loose, and you'll need to go to a repair shop to reinforce it. When washing your car, avoid spraying high-pressure water directly at the mirror base connection to prevent accelerated aging.
