There are two of them, but they work together and are integrated with the front and rear Junction Boxes (Fuse/Relay panel), but you can't just replace it, they need to be programmed for the vehicle. You can check its connections for any water intrusion, but most likely the failure is internal. The first two diagrams are the front unit and the second two are the rear unit. These are considered to be Smart Fuse/Relay Junction Boxes since they have network communications running through them.
Check the exterior lamp assemblies for any water intrusion, if there's any moisture inside where the turn signal bulbs are. Any water intrusion can short out the bulb sockets and cause failures like this as well.
