How to Fix a Loose Rearview Mirror?
3 Answers
Here are the solutions for a loose interior rearview mirror: 1. If the interior rearview mirror is loose, it is usually caused by hanging a dashcam or heavy decorations on the mirror. The solution is simple: if the looseness occurs at the mounting point on the windshield, apply some glue to secure it. If the ball joint of the mirror is loose, tighten the screw. 2. Most car rearview mirrors have an adjustable tension screw at the ball joint, allowing you to adjust the tightness of the mirror. If the mirror becomes loose, simply locate this screw and tighten it. Additionally, avoid hanging dashcams or heavy decorations on the rearview mirror, as prolonged use can lead to looseness.
The rearview mirror is loose, usually because the fixing screw is loose. I've encountered this several times. First, check the base of the rearview mirror to see if the screw position is stripped. Use a suitable wrench to gently tighten it, but don't use too much force, as it may damage the plastic parts. If the screw hole is stripped, apply a bit of threadlocker for a temporary fix. Long-term vibration is the main cause. Spend a minute or two checking before driving to avoid accidents caused by impaired vision. Tighten it casually after washing the car to extend its lifespan. If you really can't fix it, don't force it—go to a repair shop immediately. Safety is the top priority.
Last time I was driving on the highway, the rearview mirror was shaking badly and almost caused a scrape. After getting out to check, I found the base screws were loose: flip open the door's inner trim panel, locate the hex screws, and tighten them with a tool to stabilize it. If it's a new car with power adjustment, be careful not to disassemble it yourself to avoid potential short circuits. Wear gloves during the process to prevent scratches. Safety first—an unclear rearview mirror can hinder lane changes and reversing. Also, a reminder: when replacing parts, opt for branded ones for better durability. After fixing it yourself, test the door opening and closing several times to ensure it's secure before hitting the road.
