What is the repair method for a loose car rearview mirror?

First, remove the rearview mirror, apply glue to the loose area, reinstall the mirror, and check if it is stable. If not, remove it again and reinstall. Adjust the tightness of the screws to set the rearview mirror at an appropriate level. Screw location: Look upwards from the bottom of the exterior rearview mirror to find a thumb-sized hole.

I've been driving for almost twenty years and have encountered loose rearview mirrors quite a few times. First, you need to determine whether it's the housing that's loose or the entire mirror. If it's the housing, it's usually due to broken clips. You'll need to disassemble it to check if the clips are damaged. If you're doing it yourself, prepare a set of plastic pry tools and spare clips, and be careful not to scratch the car's paint when removing the housing. If the entire mirror is wobbling, it's likely that the base screws are loose. In this case, you'll need the appropriate screwdriver or socket wrench to tighten the fixing screws at the connection point between the mirror and the door. For manual rearview mirrors, this should stabilize them, but for power-adjustable mirrors, never force them—the internal gears can easily misalign. It's best to take it directly to a repair shop for a technician to recalibrate the position. Also, avoid blasting water directly into the gaps of the rearview mirror when washing the car to reduce the chances of loosening.

As a mom who drives to pick up and drop off kids, a loose rearview mirror really makes me nervous. Last week, I encountered a situation where the right mirror shook so badly during reversing that I couldn’t see clearly, so I immediately took it to the 4S shop for repair. The technician said common causes include aging plastic bases or excessive force from car washing. If you want to fix it yourself, and if the mirror can be folded, bend it to 90 degrees—you can then tighten the internal screws with a Phillips screwdriver. If it can’t be folded, don’t force it; it’s safer to visit an auto repair shop. By the way, some cars have decorative covers between the mirror and the door—you can pry them open with a bank card or fingernail to reveal the screw holes. After fixing, test the turn signal function, as the wiring connectors are also located there. I suggest avoiding temporary fixes with 502 glue, as it can corrode plastic parts and cause more trouble.

Just started as an apprentice at an auto repair shop three months ago, and we deal with side mirror issues every day. The process involves three steps: First, locate the loose point and inspect the pivot bolt under the mirror body—a 10mm socket usually does the trick. If that doesn’t work, remove the door panel to check the internal bracket nut, typically a 13mm size. Finally, examine if the hinge spring is deformed, which requires special pliers for resetting. Note: For power mirrors, always pull the fuse before working. DIY repairs carry risks—last time, a customer stripped threads using the wrong spline wrench. Parts matter too: German cars need high-carbon steel screws, while Japanese models require anti-rust washers. After repair, always readjust the mirror angle, or blind spots could become dangerously larger.
