What to Do If the Rearview Mirror Glass is Loose?

Use pliers to grip the metal shaft and rotate it appropriately, allowing the spring to pop up and secure the seat firmly. Forcing it in the opposite direction may cause damage, and after normal rotation, it might become loose when returning to position. After forcibly rotating the rearview mirror in the opposite direction, the spring is compressed, causing internal misalignment. The compressed spring cannot rebound, leading to looseness between the mirror body and the mirror base. Pry open the reinforced circular area in the middle to observe the rotating shaft. During assembly, press down on the circular metal piece until it locks into place, using the spring to tightly integrate the mirror body with the mirror base.

A few days ago, my rearview mirror also started to wobble, especially when driving on bumpy roads. I pulled over to check it, first looking to see if the screws holding the mirror in place were loose. Some cars use small-sized screws, so you need the right tool to tighten them—just don’t use too much force to avoid damaging the threads. If you can’t fix it yourself, it might be a broken internal bracket or a motor issue, especially for electrically adjustable mirrors. Later, I took it to a repair shop, and after inspection, they said it was a minor issue and fixed it for less than a hundred bucks. When washing or parking your car, try to avoid hitting the mirror—prevention is always better than dealing with an accident. Safety comes first when driving; poor rear visibility could lead to trouble when reversing, so it’s best to address any issues as soon as possible. Safety is paramount.

The shaking of the rearview mirror is mostly caused by internal structural issues, such as worn fixing clips or loose screws. I’ve tried disassembling it for inspection and found that many car designs use plastic clips that loosen over time due to aging. You can remove the mirror, carefully clean off the dust, and check if the clips are intact. If they’re damaged, buying replacement parts online isn’t expensive. For electric mirrors, pay attention to whether the wiring connections are secure—sometimes vibrations can cause poor contact, and restarting the system might resolve the issue. Don’t delay if you encounter this problem; if DIY repairs seem risky, seek a professional shop. They often use multimeters to test and ensure there are no short circuits in the wiring. Regular maintenance and inspection of these components can extend their lifespan and prevent unexpected issues.

I immediately addressed the shaking rearview mirror because unclear visibility while reversing poses a high risk of rear-end collisions. I checked if the screws were loose and tried tightening them slightly. If that doesn't work, don't force it as you might damage the entire mirror, which would be more trouble than it's worth. It's recommended to visit a professional auto repair shop to check if the internal spring or motor is faulty. The cost is minimal compared to ensuring clear and safe driving visibility. Develop a habit of checking the mirror's condition every time you park to prevent issues.
