The reasons why the Buick rearview camera is not displaying are as follows: Damaged or obstructed camera: If the camera is damaged, the image cannot be uploaded to the computer, and thus it will not display. In this case, you should go to a repair shop or a 4S store for maintenance, and if necessary, replace the camera with a new one. If there is just an obstruction blocking the camera, simply remove it. Damaged display screen: When the display screen remains black and does not start or shows distorted images, it is generally damaged. In this case, you should go to a repair shop or a 4S store for inspection and repair. Poor wire contact: If you frequently drive on rough roads, the bumpy environment may cause the internal wires of the vehicle to loosen or detach. When the wire contact is poor, the camera's image cannot be transmitted to the main unit, and the rearview camera will not display. In this case, the central control panel needs to be disassembled for inspection. No power: When the car uses lights or multimedia for a long time in a turned-off state, the battery may run out of power. When the power is insufficient or depleted, the car's multimedia system will not function, and the rearview camera will not display. In this case, simply recharge or replace the battery.

My old Buick has encountered this issue several times, and it was really frustrating at first. There are quite a few potential causes. First, the camera itself might be malfunctioning, like a dirty or obstructed lens—especially after rain when mud splashes can block the view and cause a black screen. Loose wiring connections are also common, particularly with aging wiring harnesses in the trunk area. Blown fuses are a frequent culprit, so check the relevant fuses in the fuse box near the passenger side. Software conflicts or system crashes can also be a factor—sometimes, the system won’t respond when turning the key, requiring a restart. Additionally, the body control module might have bugs, such as outdated software or missed updates causing compatibility issues. Remember, safety first: if the rearview camera isn’t working, slow down and rely on your mirrors. If needed, visit a 4S shop for a full diagnostic check of the wiring.

Last time my friend's Buick had the same issue, the rearview camera just had no signal. When troubleshooting, camera damage is often caused by water ingress or physical impact, like hitting something while reversing. Wiring issues such as connector corrosion or vibration-induced poor contact can also be the culprit—check for loose plugs near the trunk lid. A blown fuse is easy to check; the manual has a diagram showing its location in the fuse box corresponding to the reverse function. For software glitches, try a power reset or upgrading the infotainment system. I recommend starting with the simplest steps: cleaning the lens and restarting the car—it's quick and safe. If that doesn't work, then take it to a professional repair shop.

The non-display of the Buick reversing camera may involve failures in multiple components. If the camera module is damaged by moisture or high temperatures, the image will disappear directly. Transmission line issues such as short circuits or breaks in the video cable, especially accelerated wear from frequent trunk opening/closing. A blown fuse interrupts power supply to the circuit. Faults in the central control display or settings issues, such as accidentally disabling the function. System software requires regular updates to avoid bugs. It is recommended to inspect these points during maintenance to ensure reliability.
