How to Fix Electric Mirror Adjustment Failure?
3 Answers
Try operating the mirror on the other side. If both mirrors fail to function, it may be caused by a blown fuse - simply replace the fuse. If only one side mirror is damaged, this indicates an issue with the wiring or the mirror assembly itself, requiring inspection and repair at a service center.
I think the failure of power-adjustable mirrors is quite common. It could be due to stuck buttons or worn contacts that prevent signal transmission. I've encountered this issue several times myself. As a temporary fix, I manually adjust the mirror to the proper position using a small key, ensuring at least the driving visibility isn't affected. Blown fuses are also a major cause. Remember to locate the mirror-related fuse in the driver's seat fuse box, pull it out to check if it's blackened, and replace it with a new one if necessary. If it still doesn't work after replacement, it might be due to aged wiring causing a short circuit or a burnt-out motor. Avoid disassembling it yourself as you might damage more components—just drive to a 4S shop or a professional repair center and let the technician diagnose it using the circuit diagram. During regular maintenance, keep the mirrors dry to prevent water corrosion, which can help reduce such issues.
As someone who frequently tinkers with cars, I've found that rearview mirror failures often occur in the controller or connecting wires. For example, a loose plug can interrupt the current flow. Try lifting the cover of the adjustment button to check if the wiring is secure. If it's loose, press it firmly to see if functionality can be restored. Motor issues are another possibility – listen for strange noises during operation or complete failure to rotate. If manual adjustment feels smooth with little resistance, the motor is likely fine; otherwise, replacement parts may be needed. Circuit problems like poor grounding are also common. While a multimeter can test voltage, avoid DIY fixes to prevent electric shock – safety first! It's wiser to have a mechanic handle disassembly and inspection. Maintaining proper rearview mirror positioning while driving is crucial. In emergencies, adjust manually to avoid distraction.
