What to Do When the Up and Down Adjustment of the Rearview Mirror Fails?
2 Answers
When the up and down adjustment of the rearview mirror fails, there are several possible scenarios: 1. Poor button contact. The adjustment buttons for up, down, left, and right directions malfunction. In this case, first check the switch—nine times out of ten, it's dirty. Usually, cleaning it will restore normal function. Since dismantling the entire control panel is difficult, it's recommended to go directly to an auto repair shop or a 4S shop and let professionals handle the cleaning. 2. Misalignment of the white screw inside the mirror. During adjustment, the motor makes a working sound and appears to be functioning, but the adjustment fails. Solution: Insert the white screw back into the rubber sleeve. The mirror lens can be directly pried off by applying force from the bottom of the lens, pushing upward and outward. The middle of the lens has a large spherical slot—once opened, the white screw can be seen. 3. Damaged motor gears or wiring harness issues. In this situation, the only option is to visit a 4S shop or an auto repair shop, have professionals inspect and diagnose the problem, and then proceed with the appropriate repairs.
The failure of the rearview mirror's up and down adjustment is a common issue, and I think there's no need to panic right away. Try to identify the source of the problem first. Most likely, it's either a burnt-out motor or a stuck control button. I often encounter such problems. The first step is to check if the button is dirty or has any foreign objects. Try cleaning it with a soft cloth. If it's electric, check the fuse box, which might be near the door panel inside the car—refer to the manual for the exact location. If that doesn't work, the wiring might be loose or short-circuited. As a temporary fix, gently tap the base of the rearview mirror to loosen it a bit, but don't use too much force. In the long run, delaying repairs can make it hard to see behind you, leading to dangerous driving. I recommend taking it to a professional repair shop as soon as possible. For regular maintenance, remember to wipe the buttons monthly to avoid dust buildup. I suggest using a small toolkit to check the connections, saving you unnecessary expenses. The rearview mirror is like the eyes of your car; protecting it is crucial for safety, so don't ignore minor issues.
