My brake lights do not work and my turn signal also do not work. All lights are fine all fuses are good, flashers do work.

We are losing power somewhere which I think is the turn signal switch. Here is a guide to help you test for power and the wiring diagrams to help see how the system works:

Test for power though the switch. Check out the diagrams (below). Please let us know what happens.
