Where is the turn signal flasher relay switch located?

So this system does not have a turn signal flasher like older cars, the flashing is handled by the BCM, I would check around the car with the emergency flashers to make sure no bulbs are out and if not let's check the BCM fuses # 1, 3, 9, 10 and 20 in the fuse panel on the left side of the dash.
