What are the reasons for dashboard lights not working?
2 Answers
Car dashboard lights not working is mainly caused by damaged lighting bulbs, broken power supply wires, or blown fuses. Damaged lighting bulbs: If the lighting bulbs inside the dashboard are damaged, they should be replaced promptly; otherwise, it will affect the driver's usage. Some dashboard background bulbs cannot be replaced individually and require replacement of the entire dashboard assembly. Broken power supply wires: Damaged power supply wiring to the dashboard, such as open circuits or short circuits, can also cause the car dashboard lights to stop working. The solution is to replace the power supply wiring. Blown fuses: If the power supply fuse for the car dashboard is blown, the power cannot supply the dashboard normally, causing the dashboard lights to suddenly stop working. The solution is to replace the power supply fuse.
I've experienced the issue of dashboard lights not working several times, and there are quite a few possible causes. The most common one is a blown fuse, located in the fuse box under the steering wheel – you can simply replace it with a new fuse using tweezers. If the fuse is fine, it might be a burnt-out bulb, especially in older cars where filaments tend to break after prolonged use. Wiring problems, such as loose connectors or aged, damaged wires causing poor contact when driving over bumps, could also be the culprit. Unstable voltage, particularly when the alternator output is too high, can damage dashboard lights as well. Don't overlook potential faults in the dashboard itself, like water-induced short circuits or damaged internal circuit boards. Non-functional dashboard lights compromise nighttime driving safety, making it hard to see speed and warning indicators, which increases accident risks. I recommend investigating immediately upon discovery rather than waiting until problems arise. If you can't fix it yourself, a repair shop can usually resolve it within half an hour at minimal cost.
