Why is the Buick Envision dashboard not lighting up?

[DiDaniella]

The reasons for the Buick Envision dashboard lights not working are as follows: 1. The dashboard illumination bulb is damaged. 2. There is a break in the dashboard power supply wire. 3. The dashboard power supply fuse is blown. 4. The solution is to check the dashboard power supply fuse and replace it if blown; disassemble the dashboard, as the illumination bulbs are usually located at the rear of the dashboard, and replace the non-working bulb. Here is additional information about dashboard lights: 1. Indicator light on: Immediately check the odometer. If the accumulated mileage reaches or exceeds 100,000 km, the timing belt must be replaced; otherwise, it may break, causing the engine to malfunction. 2. Turning off the indicator light: After replacing the new timing belt, remove the rubber plug covering the reset switch on the odometer panel, press the internal switch with a small rod to turn off the timing belt indicator light. 3. Troubleshooting: If the indicator light does not turn off after operating the reset switch, the switch may be faulty or there may be a short circuit in the wiring. Inspect and resolve the issue. After replacing the new timing belt, also remove the odometer and reset all readings to "0."

I've encountered this issue before - pitch black instrument cluster is terrifying! Don't panic yet, first try turning on hazard lights and pull over safely. Most likely it's a blown fuse - check that small box behind the glovebox on passenger side, look for the 15-amp fuse labeled for instrument cluster, see if it's darkened. If the fuse looks fine, there's 80% chance it's either loose power wire to the cluster or loose battery terminal in trunk. Otherwise could be instrument cluster module failure - need to scan for trouble codes. Remember, while the car may still drive, don't push your luck - calling roadside assistance is the safest bet.

Yesterday my car's screen suddenly went black, and my heart was in my throat. There are two levels to this situation: simply put, it could be a blown fuse for the dashboard backlight, or more complicated, the instrument module might have crashed. Here's a down-to-earth trick—turn off the engine, lock the car, and wait ten minutes to let the onboard computer reboot completely. Sometimes it's just like a frozen phone. If that doesn't work, check the fuse box, located under the cover panel to the lower left of the steering wheel. Buick's dashboard wiring harness connectors are prone to oxidation—a quick spray of WD-40 might do the trick in a pinch.

Anyone who drives an American car knows that instrument cluster blackouts are all too common. There are five main reasons: a blown power fuse, a loose connection in the instrument cluster plug, a Body Control Module (BCM) error, a damaged instrument cluster assembly, or a short circuit in the wiring. I recommend first checking if the purple power wire from the BCM to the instrument cluster has 12 volts. By the way, those who have modified their reverse cameras are particularly prone to this issue—bundling wires together can cause signal interference, a pitfall I've personally experienced! The safest approach is still to visit a 4S shop and connect to the GDS diagnostic computer; it can pinpoint the fault in just five minutes.
