What to do if the dashboard backlight of Maxus V80 is not working?

[StTimothy]

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.

My delivery van, the Maxus V80, had the same issue last year. One morning when I started it, the dashboard was completely dark. First, I checked the light switch to confirm it wasn't accidentally turned off. Then, I opened the fuse box to locate the dashboard fuse. Using pliers, I pulled it out and found it had blown. After replacing it with a new 15A fuse, the dashboard lit up again. If the fuse keeps blowing repeatedly, you'll need to check the wiring. Some drivers in our group mentioned it might be due to the wiring harness being worn through by the steering column bracket, causing a short circuit. Another quick check is to use your phone's flashlight at night to see if the dashboard is truly not lighting up—sometimes it's just hard to see because the background is too bright. If everything else checks out, it's likely an internal issue with the dashboard, and you'll need to visit a service center for a replacement. It's best to address this kind of problem early, as driving at night without a visible dashboard can be dangerous.

I've repaired many such faults. Diagnosing non-illuminating instrument backlight usually involves three steps. First, check the light adjustment knob - there's a rotary button on the lower left of the Maxus V80's steering wheel. Second, inspect the fuse box located behind the steering wheel cover panel. Find the fuse marked with the instrument cluster icon and test it with a circuit tester or simply replace it. Third, examine the wiring connections by removing the lower steering wheel cover to check circuit continuity. I've encountered more complex cases where BCM module failure caused backlight issues, which requires diagnostic equipment to read trouble codes. Module replacement can cost over a thousand, so I recommend prioritizing the first three checks. Don't worry if you're not confident - checking fuses according to the manual is quite simple. If all else fails, visit a service station for wiring inspection.

My neighbor's V80 just had this issue fixed last month. He was driving at night when suddenly the dashboard went completely dark, which scared him so much that he drove straight to the repair shop. Actually, you can check it yourself under normal circumstances: first, turn the backlight adjustment knob located at the lower left corner of the steering wheel to make sure it's not stuck at the lowest setting. Then check the fuse—the dashboard fuse for the Maxus V80 is located in the fuse box near the driver's left knee position, which is quite deep and requires a flashlight to locate. If the dashboard lights up after replacing a blown fuse, then it's not a big issue. Another owner in our community found out it was a wiring problem—incorrectly connecting the wires while installing a dashcam caused the fuse to blow. This kind of issue requires dismantling the center console to inspect the wiring harness, which is quite troublesome. It's recommended not to tamper with it yourself; try replacing the fuse first, and if that doesn't work, send it for repair. Fixing dashboard backlight issues early is crucial—not being able to see the speedometer clearly at night can easily lead to speeding and getting a ticket.
