Which Fuse is Blown When the Central Control Screen Doesn't Light Up?
3 Answers
If the fuse for the vehicle's central control screen is blown, the screen will not light up due to lack of power supply. Simply replace the fuse in the engine compartment fuse box. The reasons why the car's central control screen does not light up are as follows: Reason 1: The central control screen system is frozen. High or low temperatures can cause system components to malfunction, leading to this situation. The screen will resume normal operation once the vehicle temperature stabilizes. Reason 2: The central control is mistakenly turned off after starting the vehicle. In this case, simply press the power button to turn it back on. Reason 3: The fuse for the vehicle's central control screen is blown, cutting off the power supply. Replace the fuse in the engine compartment fuse box to resolve the issue.
The center console screen not lighting up might not just be due to a blown fuse. I often encounter this issue in my car, and the reasons can vary. First, fuses are responsible for protecting circuits; for the center console screen, it's usually labeled as "INFO" or "RADIO" fuse, typically located in the fuse box under the dashboard or the main box under the hood. Depending on the car model, for example, in my Toyota, it might be F15, while in a Ford, it could be in the side box near the passenger seat. When checking, turn off the engine and remove the key, then inspect if the fuse is blown—a broken black wire core indicates it's burnt out. Simply replace it with a new fuse of the same amperage. However, replacing the fuse alone doesn't solve all issues. The screen not lighting up could also be due to aging wiring, control module failure, or unstable voltage. I recommend using a car test light to quickly check the continuity of the wiring. Preventive measures include avoiding random electrical installations to maintain power stability and glancing at the fuse box during each maintenance check.
As someone with some auto repair knowledge, let me tell you that a blown fuse is a common cause when the infotainment screen won't light up. Specifically, look for the fuse labeled "ENTERTAINMENT" or similar in your vehicle's fuse box, typically rated between 10A-20A. Common locations are near the driver's footwell or below the glove compartment - in cars I often work on, it's frequently labeled F10. The procedure is simple: with the engine off, use tweezers to pull out the fuse; if it appears blackened or broken, replace it with an identical specification. Never substitute with a higher amp fuse as it increases short-circuit risks. If replacement doesn't solve it, check for loose connections or power supply module issues. Safety tip: avoid working in rainy conditions to prevent electric shock. Address this promptly - otherwise you won't even have your reversing camera when backing up, which is dangerous.
