Turn signal flashers

So just to be clear when you say you hear a flasher noise, you mean when you turn the signals on you hear the clicking some times and other times you do not hear the clicking but the turn signals always work?

The turn signal relay is what makes the clicking noise but on your vehicle it uses the BCM and not a relay. So if there is no relay, then there is no clicking noise. Most customers would not be okay with their turn signals not clicking so that is reproduced by the BCM. So if yours is not clicking intermittently then the BCM is at fault for that. If it were me, I would not replace it just for this.

Let me know if you have questions. Thanks
