What Causes the Car Dashboard to Not Light Up?
2 Answers
The reason the car dashboard does not light up is due to a damaged dashboard illumination light, or an open or short circuit in the dashboard power supply wiring. Below are the functions of the car dashboard and cleaning methods: Functions of the car dashboard: The car dashboard is a device that reflects the working conditions of various vehicle systems, providing the driver with necessary operational parameter information. Cleaning methods for the car dashboard: Use a soft fiber cloth to wipe away surface dirt and dust. Clean gaps with a toothpick or cotton swab wrapped in a cloth or tissue. Soak a soft cloth in tap water to remove stubborn stains.
Oh, I've encountered this issue a few times. The most common reason for the dashboard not lighting up is a blown fuse, which can be found in the small box near the driver's seat. Another issue could be the LED bulbs, which may have aged or burned out after prolonged use. Poor wiring contact is also quite common, such as loosening or short-circuiting when the car vibrates heavily. If the car battery is low or the alternator malfunctions, unstable voltage can cause problems with the lighting system. Occasionally, a stuck control module or relay can also make the dashboard stop working. The important thing is, when the dashboard doesn't light up, you can't see the speedometer, fuel gauge, or warning lights, which is especially dangerous when driving on the highway. You should immediately pull over to check or go to a repair shop. During regular maintenance, I usually ask the technician to check the lights as well, just as a precaution.
