The reasons for the Enclave being silent are as follows: Dead battery: The electronic devices in the car are powered by the battery. If the car battery is depleted, the audio system will naturally have no sound. In this case, simply charging the battery will resolve the issue. Audio plug disconnected: If the audio plug becomes disconnected when the car goes over bumpy roads, the audio system will also have no sound. In this situation, the audio system needs to be removed and reinstalled. Volume turned off or in mute mode: This situation is relatively simple to resolve. Just turn up the volume or disable the mute mode of the audio system.

After driving for so many years, my Envision has also experienced sound issues. The most common problem is with the audio settings, such as accidentally pressing the mute button on the steering wheel or enabling mute mode in the system menu. Sometimes, unstable battery voltage can cause the entire vehicle to power off and restart, causing the sound function to get stuck. Additionally, blown fuse for the horn is quite common, located in the fuse box under the hood, which isn't hard to check. Software bugs are also not rare, especially after upgrading the car's system, which can lead to conflicts. My suggestion is to first turn off the engine and lock the car, wait a few minutes, and then restart it to see if it works; if not, just head straight to the 4S shop—they have professional tools to test the circuits. Regular maintenance should pay extra attention to electrical components to prevent issues from piling up and becoming safety hazards.

I enjoy tinkering with cars, and when encountering non-functional Buick Enclave horns, it's often due to software or system malfunctions. Bluetooth connections with phones may interfere with the vehicle's original audio output, or the multimedia interface could be stuck in mute mode. On the hardware side, poor relay contact can obstruct signal transmission, and blown fuses are a common issue. When conducting self-checks, refer to the manual to locate the fuse and simply replace it. Don't overlook connecting to the OBD diagnostic port with a computer to check error codes. Battery aging can also cause intermittent failures, so regular testing is recommended. If safety warnings are silent while driving, seek professional repair immediately—don't take risks.

It's really annoying when the horn doesn't work while commuting in the Enclave. Usually, it's a setting issue—the mute button on the steering wheel might have been accidentally pressed, or the mute icon on the audio main page is lit up. Try turning the car off and restarting it, then adjust the volume knob. Sometimes, low battery power can cause the system to reset, and it might recover after charging. Bluetooth connection issues can also mess up the audio output. If all else fails, check the fuse box section in the manual. Don't wait too long—driving without warning sounds is quite dangerous.
