Why is the rearview mirror heating not working in the Magotan?
2 Answers
It may be due to incorrect operation. The button is located at the lower 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 relevant information about the rearview mirror heating function: Function: The rearview mirror heating function ensures that the outer rearview mirror remains clear during rain, snow, or fog by heating the electric heating wires embedded behind the mirror. Working Principle: The electric heating rearview mirror works by installing an electric heating element (heating film) inside the mirror on both sides. In rainy or snowy weather, when the driver activates the rearview mirror heating function, the heating element quickly reaches a fixed temperature, usually between 35-60 degrees Celsius, within a few minutes, thereby defogging and defrosting the mirror.
I've been driving a Volkswagen Magotan for several years and have encountered the rearview mirror heating not working a few times. Generally, there are several possible reasons. The most common is a blown fuse, located in the fuse box in the engine compartment—you need to find the correct position and replace it with a new one. Sometimes, the heating switch is faulty, especially in older models where the button may have poor contact after prolonged use. There could also be wiring issues, particularly in winter when temperature fluctuations are significant, leading to oxidation or broken wires—this requires careful inspection of the wiring harness connections. Or, the heating element itself might be faulty; you can remove the rearview mirror casing to check for any damage. I've seen many car owners on forums sharing similar issues, and the connector near the Magotan's rear door handle is also prone to loosening—tightening it often resolves the problem. Overall, these issues aren't difficult to handle, but if you're unsure, it's best to visit a professional shop for inspection, as foggy rearview mirrors can significantly impact safety.
