Why is the Malibu display screen not lighting up?
2 Answers
If the Malibu's central control screen does not light up occasionally, it is normal because when starting the car, the electricity is momentarily used for ignition, resulting in lower voltage. If it frequently does not light up, you should check whether the power supply to the display screen is normal. If the power supply is abnormal, please replace the power supply module and then check whether the wiring harness contact is good. Additional Information: 1. Car Central Control: The car central control is the place where comfort and entertainment devices such as car air conditioning and audio are controlled. The car central control includes the central control door lock system, through which the driver can control the switching of all car doors and the window lifting system. 2. Central Control Door Lock System: The central control door lock system mainly has three functions: central control, speed control, and individual control. The driver can control the switching of all door locks. At the same time, when the driving speed reaches a certain level, the doors automatically lock. For other doors, there are independent switches that can individually control their own doors.
Yesterday when I was driving my Malibu, the display suddenly went dark, which gave me a start. But I quickly calmed down, knowing that common issues could be a blown fuse or loose wiring. I opened the engine compartment's fuse box myself, referred to the owner's manual for the correct position, and replaced the fuse—the screen lit up right after. If that hadn't worked, it might have been a hardware failure in the screen or the infotainment system freezing; in that case, trying to restart the vehicle by turning off the ignition, waiting a few minutes, and then starting it again might have restored the screen. The display controls music and navigation, so a black screen is quite annoying. Fortunately, the Malibu is designed simply, and regular checks of the fuse box can prevent such issues. In short, don't rush to the repair shop—first troubleshoot basic problems to save on costs. After all, a non-functional screen doesn't affect driving safety, though it does make operations less convenient. Remember to pay attention to the display's response during startup, as this can quickly pinpoint the source of the problem. If you encounter a similar situation, I recommend taking it step by step.
