Why can't the rearview mirror return to its original position after folding down?

It may be because the car is not equipped with an automatic folding function, so the rearview mirror cannot automatically return to its original position. Here is an introduction to rearview mirror folding: 1. Introduction: Nowadays, rearview mirrors on mid-range and high-end cars are basically foldable. The folding function is divided into two types: manual and automatic. For manual folding, the driver must reach out the window or get out of the car to fold the mirror when needed, which is both inconvenient and unsafe. This type of folding rearview mirror is now rare. 2. Function: Folding the rearview mirror can save a lot of space and also prevent the car from suffering the pain of 'broken ears'. During driving, accidents are inevitable. As the widest part installed on the vehicle, the rearview mirror is most susceptible to impact in case of a scrape. To minimize scratches, the rearview mirror needs to have a folding function.

Recently, my car also encountered the issue of inaccurate mirror repositioning. This situation is usually related to the memory function of power-adjustable mirrors. Many models come with position memory modules, and settings can easily be lost if the vehicle loses power or the system resets. It could also be due to wear on the plastic gears in the mirror base, especially for vehicles where the mirrors are frequently folded manually. I recommend first trying to long-press the seat memory button to reset the position. If that doesn't work, the motor gear assembly needs to be checked. Last time I went to the 4S shop for repairs, the technician mentioned that insufficient lubrication could also cause repositioning deviations—they applied specialized grease to the gears and resolved the issue. It's best not to attempt disassembly yourself for such problems, as the wiring inside the mirrors is quite fragile.

The rearview mirror not returning to its original position significantly affects the driving experience. My car had the same issue before. There are three main aspects to consider: a faulty control module can cause the system to forget the original position; stuck transmission gears in the mirror base may need cleaning; or poor wiring contact could lead to signal interruption. It's recommended to first reset the memory function via the vehicle settings menu—note that some cars require this operation while in P (Park) mode. If you hear the motor spinning without engagement during adjustment, it's likely an issue with the transmission mechanism. I later found that regularly using compressed air to blow out dust from the mirror pivot gaps can prevent this problem, as dust buildup affects gear meshing precision. Don't rush to replace the entire assembly; in most cases, a simple cleaning can restore functionality.

Abnormal rearview mirror reset is quite common. The core issues lie in the position memory module and mechanical transmission. First, check if the electric adjustment button has poor contact, and try switching to reverse mode multiple times to trigger a reset. Then inspect the base of the mirror pivot for any foreign objects obstructing rotation. Volkswagen models are prone to losing memory positions due to software bugs, requiring recalibration with a diagnostic tool. Japanese cars often experience gear wear, especially older models. For DIY repairs, carefully pry open the base housing and apply precision instrument lubricant to the gear set. After resetting, use a marker to note the initial position for easy observation.

Have you encountered the issue where the mirror doesn't return to its original position properly after tilting down for reverse gear? In most cases, this is caused by accumulated errors in the transmission mechanism, as electric mirrors have a certain tolerance range for reset accuracy. You can first try disconnecting the negative battery terminal for three minutes to reset the system. If the offset persists, focus on checking whether the limit sensors and Hall elements have shifted. From my experience, aftermarket dash cams' electromagnetic interference can also affect reset accuracy. During maintenance, it's advisable to have a technician test the motor resistance value - abnormal wear will create a dragging sensation. When adjusting, remember to hold the memory button until you hear a click sound to ensure successful position storage.
