Here are the solutions for the dashboard backlight of Maxus V80 not working: 1. The dashboard backlight switch is not turned on: The solution is to simply turn on the backlight switch. 2. The dashboard circuit board is burnt: You need to replace the dashboard with a new one to use it. 3. The dashboard illumination light is damaged: Disassemble the dashboard. The illumination lights are usually located at the back of the dashboard. Replace the non-working illumination light. 4. The dashboard power supply fuse is blown: Check the dashboard's electrical fuse. If it's faulty, replace it with a new one. Additional information: The dashboard is a high-definition flat panel or structural component that installs instruments and related devices. It can be categorized into screen-type dashboard, frame-type dashboard, channel-type dashboard, and cabinet-type dashboard based on its form.
Last time I drove the Maxus V80, I also encountered the issue of the dashboard backlight not working, which was particularly nerve-wracking when driving on the highway at night. Don’t rush to dismantle the dashboard just yet—you can check a few things first: see if the brightness adjustment knob for the lights was accidentally turned off; this knob is located below the left side of the steering wheel. Then, open the fuse box near the driver’s left knee area and look for the fuse related to the dashboard backlight. Refer to the icons on the cover or the manual to locate the exact position. If the fuse is blown, simply replace it with a new one of the same specification. If everything seems normal, the issue might be a loose connector behind the dashboard, requiring the removal of the dashboard panel to reconnect it securely. In my case, it was a poor connection—once I reinserted it firmly, the backlight worked again. If you can’t figure it out, it’s safer to take it to a 4S shop for professional diagnosis, as DIY disassembly can easily damage the clips.
This issue is quite common in our repair shop, and I've dealt with the MAXUS V80's backlight failure several times. First, rule out the possibility that the dimmer switch is turned off—there's a brightness adjustment knob below the steering wheel on the left side. Next, check the fuse box. There's a black plastic cover panel below the steering wheel; open it and look for the fuse related to the instrument panel. If you find a blown fuse, replace it with one of the same amperage. If that's not the issue, you'll need to inspect the wiring. The wiring harness between the steering wheel and the instrument panel may have wear damage or poor contact. The most troublesome scenario is aging backlight strips inside the instrument panel, which requires removing the entire dashboard for replacement. I recommend trying to replace the fuse yourself first, but for dashboard removal, be sure to consult a professional technician. Attempting it yourself can easily break the clips and may pose safety hazards.
