What is the reason for the normal operation of the turn signal but no prompt sound in the Buick Excelle?

The reason for the absence of sound in the Buick Excelle's turn signal may be due to it being set to mute or incompatibility with the original vehicle protocol after installing a navigation system. If the Buick Excelle's turn signal has no sound, it might be set to mute. This can be adjusted via the buttons below the central control display. Press the MENU button, select the vehicle option, click on sound settings, and find the turn signal option to make adjustments. The turn signal sound has two adjustable levels. Within the vehicle settings, you can also configure functions such as air conditioning and air quality, lights and door locks, remote keys, and collision warning alerts. Normally, the Buick Excelle's turn signal emits a ticking sound from the radio. If a navigation system is installed or the radio is tampered with, it may result in the turn signal having no sound. Particularly, installing a navigation system that is incompatible with the original vehicle protocol can cause the original vehicle protocol to no longer support the navigation system. If this is the issue, replacing the navigation system with one compatible with the original vehicle protocol is necessary to resolve the problem. To replace the turn signal bulb in the Buick Excelle, first open the engine hood. Near the lamp socket inside the engine compartment, you can see the lamp cover. The bulb's rear cover should be easily accessible from the inner side of the bumper. Turn the lamp cover counterclockwise to remove it, then rotate the lamp socket counterclockwise to detach it and remove it from the reflector housing. Detach the bulb from the socket, replace it with a new one, insert it into the socket, ensuring the two lugs snap into the reflector housing, and rotate clockwise to secure. Rotate the lamp holder clockwise until it can't turn anymore, then install the lamp cover by rotating it clockwise to complete the installation.
As a long-time owner of an Excelle, I recently encountered the issue of no turn signal audible alert while the lights still flash, which bothered me for days. Possible causes include: the small speaker producing the alert sound (professionally called a buzzer) being faulty or loose; poor wiring contact, such as aged connectors coming apart; or a blown fuse, which is common during hot summers when overload causes it to melt. Another possibility is the vehicle's audio system integrating the alert sound, with a software conflict muting it. I checked it myself—first locating the fuse box to inspect and replace the corresponding fuse, which fixed the problem. If that doesn’t work, a repair shop would need to test the circuit or replace the buzzer component. No sound is troublesome, making it easy to forget to turn off the signal when changing lanes, creating a safety hazard. I recommend not delaying repairs, as small issues can escalate into major fixes. By the way, regular maintenance checks on these small electronic components can prevent many headaches.
While driving my Buick Excelle for daily commutes, I noticed the turn signal has no audible alert, though the lights work normally. This makes me constantly worry about forgetting to turn them off during long trips. Possible causes include: a failed buzzer component inside the vehicle control module (prone to aging and cracking), wiring short circuits or corrosion interrupting signals, blown fuses (especially from current surges during frequent signaling), or accidentally disabling the alert sound in system settings. I once disassembled the dashboard myself and found a loose wire connection – tightening it fixed the issue. Solutions aren’t complicated: first, restart the car to reset software; then check fuses or basic wiring; if unresolved, have a technician diagnose with professional tools. Driving without audio cues is risky, especially on nighttime highways where oversights happen easily. Minimize using turn signals in rain to reduce moisture-related corrosion.
I just bought an Excelle not long ago and encountered a situation where the turn signal has no audible alert but the light still flashes. It's really annoying having to constantly check the dashboard to confirm if the light is off or not. Possible causes could be as simple as a faulty buzzer or poor wiring connection; sometimes it's a blown fuse; or it might be a bug in the audio system affecting sound output. It's recommended to check the vehicle settings menu to see if the alert sound was turned off; or try restarting the system to refresh functions. If you're handy, you can pop the hood and check the fuse box to replace the fuse - many vehicle manuals clearly mark its location. If you can't fix it yourself, don't stubbornly keep driving as it poses safety risks. Taking it to a repair shop to check the circuit won't cost much time or money.
