I need to get some general information from you. First, do any of the rear lights work? For example, the parking lights, license plate light and so on. Next, does the center high mounted brake light work?
I have attached three pics below. The first one shows where the fuses are located as well as the signal relays. Take a look and check those fuses and relays.
The second and third pics are where the wiring goes to make everything work. I attached them so you can see that once power leaves the signal switch (including brakes) it is directed to the rear lights and front signal lights.
Since you lost everything at once, I doubt it is a ground issue. At first, I suspected a fuse or relay. However, there are two power supplies, one for the signals and one for the hazard. It would be unlikely that both would fail at the same time. So, that leads me to the switch itself.
Let me know what you find with fuses and relays first. After that, we may need to start tracing the wiring.
Here are a few links you may find helpful:
