What's the reason for the automatic rearview mirror not opening?
2 Answers
The reason the automatic rearview mirror won't open may be due to wiring or fuse issues. Below is relevant information about rearview mirrors: 1. Composition of rearview mirrors: Vehicles are generally equipped with anti-glare rearview mirrors inside the cabin, consisting of a special mirror, two photodiodes, and an electronic controller. The electronic controller receives signals from the photodiodes for both front and rear light. 2. Function: Most vehicles have three rearview mirrors. Drivers typically glance at them hundreds of times daily while driving. With the help of car rearview mirrors, drivers can expand their field of vision, indirectly observing conditions behind, beside, and below the vehicle. Therefore, car rearview mirrors play a crucial role for drivers.
Last time my side mirror got stuck and wouldn't open, which really worried me. Without it extended, it's particularly dangerous when making turns since you can't see the sides clearly. There are three common causes: first, the motor might be broken or the gears jammed, especially in winter when ice forms or dust accumulates; second, the wiring might be old and short-circuited, or the fuse might be blown—these aren't hard to check; third, the button or control module might be malfunctioning, and you might need to restart the vehicle. I suggest not forcing it open, as you might damage the mirror. I learned this the hard way, but later the repair shop fixed it for me. Regularly cleaning the base of the side mirror to prevent dust and water buildup can help avoid these issues. Driving safety comes first—getting it fixed early gives peace of mind and prevents accidents.
