Hi,
If none of the brake lights are working, check fuse 11 in the under-hood fuse box. If the fuse is good, confirm there is power to and from it. If there is, chances are it is the switch. Here is a link explaining how to test for power:

The switch is located under the dash at the top of the brake pedal. There will be two wires going to it. One is white with a tan tracer that sends power to the bulbs and the other is pink with a dark blue tracer that is the power supply from fuse 11. To confirm the switch is bad, confirm there is power to the pink/dark blue wire. It should have 12v at all times. If you do, actuate the brake pedal and check the white/tan wire for power with the brake pedal pressed. If there is power in and not out from the switch, replace the switch.
I attached the wiring schematic below for you to reference and highlighted the wiring involved.
Let me know what you find or how I can help.
Take care,
Joe
