Tail brake lights not working

Hello all,

I have a 2019 Toyota Tundra TRD Pro. The brake lights and turn signals were suddenly not working. (After driving in heavy down pour) The third brake light (above cab) does work. Running lights work, reverse lights work. In the beginning turn signals did not work, but after disconnecting battery then reconnecting the turn signals returned but still no braking lights. I have replaced bulbs, checked fuses both under hood and under driver side dash. I have looked at the wiring harnesses and sockets for corrosion. I have checked the brake stop switch to ensure it is engaging properly, on top of this the third brake light is working. I’m curious if anyone has had a similar issue or any information. Thank you for all the help!!
