What's the matter if one side of the electric rearview mirror cannot fold back?

Motor or gear damage. The following is a related introduction to the rearview mirror: Overview: The car rearview mirror is located on the left and right sides of the car's head and the front of the car's interior. The car rearview mirror reflects the situation behind, beside, and below the car, allowing the driver to indirectly see these positions. It plays the role of "the second eye" and can expand the driver's field of vision. Precautions: The car rearview mirror is an important safety component, and its mirror surface, shape, and operation are all quite particular. There are corresponding industry standards for the quality and installation of rearview mirrors, which cannot be changed at will.

I've been driving for over a decade and often encounter minor issues, like one side of the power folding mirror not retracting, which is quite annoying. The most common causes are a burnt-out motor or dirt accumulation inside – too much dust buildup can cause it to jam. Additionally, aging wiring or short circuits may prevent signal transmission, especially in older cars. My suggestion is to first try manually pushing the mirror body to see if it can reset; if that doesn't work, check the car's fuse box for the corresponding mirror fuse to see if it's blown. Also, listen for any unusual noises – if present, it might indicate gear wear. Don't ignore this issue, as mirrors that won't retract can easily get scraped when parking. Regular cleaning of mirror gaps can prevent this. When facing similar malfunctions, avoid forcing it; it's best to have a professional shop inspect it to avoid spending more on repairs for damaged parts.

I'm a car enthusiast who enjoys tinkering with vehicle repairs, and I've encountered situations where the side mirror wouldn't fold. This is often due to loose wire connections or motor burnout from overheating, especially when frequently driving in rainy conditions which can corrode the wiring. I've tried removing the mirror cover to clean off rust or apply lubricant to resolve sticking issues. However, be careful not to touch the circuit board—use a multimeter to check for current. If it's a control module failure, you'll need to replace the part. It's advisable to keep a mirror cover as protection and check if the battery voltage is stable when issues arise, as it affects the entire system. Simple DIY can save money, but for complex problems, it's safer to visit a 4S shop to avoid risking damage to other functions.

Having driven for over 40 years, my experience tells me that when the side mirror fails to fold back, it's mostly due to switch failure or being frozen stuck, especially common in winter. Don't attempt to fix it yourself as you might damage the mechanical structure and increase repair costs. Drive to a professional repair shop immediately where they can check for wiring or motor issues with proper equipment. Regular maintenance of parking positions is advised to avoid damage from extreme sun exposure or freezing.

As a young car owner, my new car comes with smart folding mirrors. Sometimes one side may not fold, which could be due to a system bug or software lag. Try restarting the car's system, or check if the 12V battery has low voltage causing control failure. If it's a hardware issue like sensor abnormality, simply replace the component. Occasionally, electromagnetic interference may also cause misjudgment in operation—disconnect the power for a few minutes after parking to reset. Updating the system firmware can reduce such issues, and regularly checking the vehicle's system health is recommended.

After years of driving, I've found that a side mirror failing to fold back is often due to gear damage or foreign object obstruction, such as small stones entering the mirror slot. First, check if the other side is functioning normally to determine if it's a systemic issue. It's recommended to clean the mirror edges with a damp cloth to see if it helps, avoiding forceful pushing; if ineffective, the drive motor might be burnt out and require replacement. Keep the mirror dry to prevent rust and reduce failure rates. Long-term neglect can affect driving safety, so repairs should be done as soon as possible.
