Why is the light under the mirror of Haval H6 always on?

The reasons and solutions for the light under the mirror of Haval H6 always being on are as follows: Electronic Stability Control (ESC) system malfunction: The light under the mirror of Haval H6 is the skid light. If it remains on, it indicates a malfunction in the Electronic Stability Control system. You can first turn off the ESC switch, then turn it back on, shut off the engine and the vehicle's power, wait for about a minute, and then restart the engine to see if the light remains on. In most cases, no further action is needed, and simply clearing the fault code will resolve the issue. Sensor malfunction or instrument control unit failure: However, it could also be due to a sensor malfunction or instrument control unit failure. In such cases, the damaged components need to be replaced.
I had the same issue when I first drove my Haval H6 - that small light under the side mirror just wouldn't turn off, which really stressed me out. Later I found there are mainly three causes: if the door lock sensor fails, the vehicle computer mistakenly thinks the door isn't closed and keeps the light on; wiring ground short circuits are particularly common, especially when rodents chew the wires or water gets in during car washes; and faulty door control modules can send wrong signals too. In my case, I did the troubleshooting myself - first repeatedly opened and closed all four doors to check response, then peeled back the door seal to inspect the wiring. If your car is still under warranty, just take it to the 4S shop for reprogramming - never attempt to disassemble the mirror assembly yourself as it's quite delicate inside. Remember to keep your key fob away too, as sometimes it can accidentally trigger the system when within sensing range.
I've seen this situation way too often in repair shops. The light under the Haval H6's rearview mirror is actually a welcome light, and if it stays on constantly, it's most likely a wiring issue. Many people install dash cams with improper wiring, pinching the cables at the door hinge area—over time, the insulation wears out and causes a short circuit. Another less common reason is loose connectors when installing automatic window lifters, which can interfere with signal transmission. I recommend first pulling out the fuse box and testing with a 10A fuse, then checking the door panel connectors for water stains or corrosion. If you're handling it yourself, disconnecting the negative terminal of the battery for ten minutes to reset the system might help. However, fixing this requires removing the door trim panel, and the plastic clips are very prone to breaking—if you're inexperienced, it's best to leave it to a professional.
