Is the Central Control Screen Not Lighting Up Due to a Fuse Failure?
2 Answers
If the central control screen is not lighting up, it may be due to a fuse failure caused by excessive load leading to the fuse blowing. Below is relevant information: Location: The fuse is located under the interior trim panel on the side of the main driver's central console. Its working principle involves electromagnetic induction, where the conductor cuts the magnetic field lines to generate an electric potential, converting the mechanical energy of the prime mover into electrical energy output. The fuse consists of a fuse element, electrode parts, and a support structure. Classification: Fuses can be categorized into flat-head tubular fuses, pointed-head tubular fuses, guillotine fuses, screw-type fuses, blade-type fuses, flat-plate fuses, wrapped fuses, and surface-mount fuses. Their function is to quickly melt when the circuit current exceeds twice the fuse's rated current, thereby protecting the circuit.
Last time I was driving, my center console screen suddenly went black, which was really frustrating. I looked into it and found that a blown fuse is indeed a common cause, as fuses are designed to break and protect the circuit from overload. The fuse box was hidden under the driver's seat, so I pulled it out and checked the fuse labeled 'INFO'—it was indeed melted. After replacing it with a new one, the screen came back on. However, the fuse isn't always the culprit; sometimes the screen itself is faulty or there's poor contact in the wiring, like my friend's car where a loose plug was the issue. Additionally, if the vehicle has been modified or got damp after heavy rain, a short circuit could also cause problems. So, I recommend car owners first check the fuse box themselves, locate the corresponding fuse, and try replacing it—it's low-cost and time-saving. If the screen still doesn't light up, then it's best to visit a professional shop to diagnose other possible issues, to avoid being stuck without navigation on the road. Regular cleaning of the electrical system can also help reduce such troubles.
