What is the reason why the rearview mirror of Mercedes-Benz e300l suddenly cannot be folded?

The reasons why it cannot be automatically folded: whether the rearview mirror is stuck by debris such as sand, and the debris needs to be cleaned; whether the rearview mirror is out of power, and the battery needs to be replaced; whether the motor of the rearview mirror is damaged, and a new one needs to be replaced if it is broken. The following are related introductions: 1. Function: The rearview mirror can increase the passing space when the vehicle meets another car in a narrow section of the road, and it can also protect the rearview mirror from damage. 2. Other reasons: If you feel the vibration of the motor working but the rearview mirror does not move, it proves that the gear mechanism for opening and closing is damaged. If you do not feel the vibration of the motor working and there is still no vibration after patting it a few times, it means that the motor is faulty or there is a problem with the circuit. Circuit problems are generally caused by switch damage or fuse burnout.
A few days ago, my Mercedes-Benz E300L also encountered the sudden problem of the rearview mirror not folding, which was really annoying. I think the most likely causes are a blown fuse or poor circuit contact. This car uses an electric folding system, with wiring connected to the rearview mirror and the relay of the driver's door switch. The fuse is located in the fuse box, usually near the foot mat area. If a fuse blows, it will cut off the power. Another possibility is aging wiring or loose connectors, such as water seeping in during car washing causing a short circuit. Last time this happened to my car, I manually checked the fuses and found a small 10A fuse had blown. After replacing it, everything returned to normal. For novice car owners, I suggest not attempting to disassemble it yourself, as it's easy to damage other components. It's safer to ask a car-savvy friend for help or visit a 4S shop. If such minor faults are not addressed promptly, driving with them can be quite worrisome.
As a car enthusiast, I've encountered rearview mirror folding malfunctions several times, especially with motor-driven models like the Mercedes-Benz E300L. The issue might stem from the mirror motor itself getting stuck or burned out. Inside, there are gears and motor components that can accumulate dust or suffer from moisture over time, causing the gears to seize and the motor to overheat and stop when activated. Related problems include unstable signal transmission from the door control unit, such as worn-out switch contacts, leading to unresponsiveness when pressing the folding button. This is more common in winter, especially for friends in the north whose cars have been frozen by ice and snow. I remember the mechanic suggesting regular cleaning of the mirror gaps to prevent this. For self-inspection, you can gently push the mirror to test its flexibility, but avoid forcing it to prevent damage. Address any issues early to avoid regrets when stranded on the road.
