What to Do When the Dashboard Doesn't Light Up but the Car Can Start?

The possible reasons for the dashboard not lighting up include: failure or damage of the dashboard illumination light; open circuit in the dashboard power supply wire; blown fuse of the dashboard power supply. Checking these aspects can help troubleshoot and resolve the issue. Here are some precautions: Regular maintenance of the dashboard: Avoid using rough or hard cloths or fingers to touch the dashboard casually to prevent fingerprints, scratches, and abrasions. It is advisable to prepare appropriate specialized cleaning supplies and perform regular maintenance on the dashboard. Applying an anti-scratch protective film: You can also try applying an anti-scratch protective film on the dashboard screen. There are various types of dashboard protective films available, and it is recommended to choose a static cling film without adhesive on the back. If the film is applied incorrectly, it can be removed and reapplied without causing any damage to the dashboard screen, and it can also prevent accidental scratches during future cleaning.
Once when I was driving to work, after starting the car, I found the dashboard completely dark, but the car could start and drive normally. It was quite scary, so I quickly pulled over to check. At first, I thought the dashboard fuse had blown. I opened the hood, located the fuse box, pulled out the corresponding small fuse, and sure enough, it had melted. Replacing it with a spare fuse solved the problem. Actually, besides fuses, loose wiring harness connectors for the dashboard are also common, especially after car washes when water can get in and oxidize the pins. Another possibility is a malfunction in the dashboard backlight circuit, which is particularly concerning when driving at night—without dashboard display, it affects checking speed and fuel levels. I recommend checking the fuse first; if that doesn’t solve it, take it to a professional shop to inspect the wiring, as it’s crucial for driving safety.
