What could be the reason for the non-functioning rearview mirror heating in the Magotan?

It may be due to incorrect operation. The button is located at the bottom left of the central control screen. As long as the engine is running, pressing this button will gradually heat the rearview mirror. Below is some related information about rearview mirror heating: 1. Rearview Mirror Heating Function: The rearview mirror heating function refers to the ability of the exterior rearview mirrors to be heated via electric heating wires embedded behind the mirror surface when driving in rainy, snowy, or foggy weather, ensuring a clear mirror surface. 2. How Rearview Mirror Heating Works: The working principle of electric rearview mirror heating involves installing an electric heating element (heating film) inside the mirror lenses of both rearview mirrors. In rainy or snowy weather, when the driver activates the rearview mirror heating function, the heating element rapidly heats up to a fixed temperature, usually between 35-60 degrees Celsius, within a few minutes, thereby heating the mirror surface to remove fog and frost.
I am a person with over a decade of car repair experience. If the rearview mirror heating on a Magotan isn't working, the most common issue is a blown fuse, which happens most frequently during light rain when moisture causes unstable current and blows the fuse. I recommend first opening the fuse box to locate the corresponding marked position, usually near the driver's seat, and pulling it out to check if it's blackened or blown. If the fuse is fine, the heating element might be faulty, such as aged or broken heating wires or rusted connectors causing poor contact, requiring the mirror to be disassembled for inspection or resistance measurement. Alternatively, the switch button might be malfunctioning—try pressing it a few times to test the response. Circuit relay failures are also quite common; the relay is in the engine compartment fuse box, and stuck contacts can prevent power flow. I've also seen cases where the door wiring harness was worn out from repeated opening and closing. In any case, don't ignore this issue—driving in the rain with poor visibility significantly increases danger. It's best to have it checked at a professional shop as soon as possible, as DIY attempts can easily damage other components.
I just bought a used Magotan, and the sudden failure of the rearview mirror heating really gave me a scare. After checking myself, I found the fuse was blown. Replacing it with a new one fixed the issue immediately—it's conveniently located in the small box to the left of the dashboard. If it hadn't been the fuse, the problem might have been a faulty heating element or oxidized switch contacts, which would require testing with a multimeter to check for continuity. Sometimes, the wiring for the rearview mirrors can have loose connections, especially after car washes where water ingress can cause issues. That experience taught me the importance of routine maintenance: a quick monthly check of the fuses can prevent bigger problems. I suggest you try it too—it saves time and avoids surprises. Driving on the highway in the rain without functional mirrors is quite dangerous, so remember to address any issues early and not procrastinate.
