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.
