Directional Flasher

LED brake and front turn signal lights will cause some flasher units to not function correctly.

There are many reasons why the TS are not working.

you need to get a wiring diagram as mentioned earlier.

Something you can do at this moment is with the key in the run position, headlights off, brake not applied, turn the TS switch to one side. If the brake light on the side you turned the switch to lights then that is a clue. Check the front turn signal on the same side also. Repeat for the other direction

Then report back
