What causes the Audi car's rearview mirror to fail to open?

Audi rearview mirror may fail to open due to reasons such as extremely low temperatures or dust accumulation in the extension mechanism increasing resistance. Damaged rearview mirror switch: First, check the fuse of the rearview mirror folding circuit. If the fuse is intact, it is highly likely that the rearview mirror switch is damaged. Damaged gear mechanism: You can ask someone to assist in operating the rearview mirror switch from inside the car while you place your hand on the rearview mirror to feel if the motor inside is working. If you feel the motor's vibration but the rearview mirror does not move, it indicates that the opening and closing gear mechanism is damaged.
I used to drive an Audi and encountered the issue of the rearview mirror not opening several times, mostly due to electrical system malfunctions. For example, the motor may wear out and age, causing it to rotate poorly, especially with Audi's automatic folding feature, which tends to get stuck after prolonged use. Wiring issues are also common—connectors getting wet in the rain and causing short circuits, or fuses blowing. There's a fuse box near the driver's footwell; just check the fuse labeled for the rearview mirror. Another possibility is poor contact in the switch button—try pressing it a few more times. If the control module fails, it becomes more complicated and requires professional diagnostic tools at a repair shop. A non-opening rearview mirror is extremely dangerous, as it obstructs visibility of rear traffic during high-speed driving. I recommend regular maintenance to prevent this.
