What Causes the Rearview Mirror Not to Fold Automatically When Locking the Car?
2 Answers
Reasons for the failure of the automatic folding function of the rearview mirror: 1. The battery is disconnected or dead: In this case, the exterior rearview mirror must be reset to function properly. The specific reset method is to manually operate the folding button. 2. After setting "fold the rearview mirror when locking the car," manual folding was performed: In this case, after unlocking the vehicle, the exterior rearview mirror will not automatically unfold. You need to enter the car and press the button on the door to manually unfold the exterior rearview mirror. The role of the automatic folding function of the rearview mirror: 1. As the widest component installed on the vehicle, the rearview mirror is most susceptible to impact in the event of a side collision. To minimize scratches, the rearview mirror needs to have a folding function. 2. A rearview mirror with a folding function can be retracted when passing through narrow sections, improving the vehicle's passability. When the driver leaves the car, the rearview mirror can also be folded, not only protecting the mirror surface but also reducing parking space, effectively avoiding scratches.
I've also thought about this issue when encountering mirrors not automatically folding after locking the car. Common reasons include incorrect vehicle settings being saved, such as the mirror folding option in the memory seat function being accidentally turned off. Or there might be a minor system software bug, like settings not being synchronized after the last update, causing the lock signal not to trigger the folding. Additionally, on the hardware side, it could be that the folding motor is stuck or the small gears are worn out, especially after long-term use where dust accumulation can easily cause problems. Another possibility is a blown fuse or insufficient battery power affecting the current supply, which can be easily checked in the fuse box. It's recommended to first try resetting the memory function, and if that doesn't work, visit a 4S shop to check the wiring and sensors, so as not to delay daily convenience. Regular cleaning of the mirror gaps can prevent such issues.
