Hi and thanks for using 2CarPros.
The body control module, (BCM) is responsible for controlling the signals and flashers. In older vehicles, there was a flasher that made the noise. However, on your vehicle there is not one. As far as the clicking, the sound is sent through the driver's side door speaker. If you have changed the factory radio, that is the problem. It could also be a bad speaker.
I hope this info is helpful. Let me know if you have other questions.
