I have done like some said and changed turn switch , nope didn't work. changed every fuse and relay on this unit. no power going to fuses for brake lights and if you jump them with direct power at fuse they come on and stay on so that lets broken wire out to lights all 3 light up. Changed brake light switch . Unit has 200,675 miles on it still runs like a top. this issue started out of the blue this past Sunday . Any help would be appreciated.

Good morning,

I attached the diagram of the fuse block for you for the brake lights.

The fuse block is fed from mega fuse 1 in the battery junction block under the hood. That provides power to that fuse box. Check that fuse for power on both sides.

I attached a picture of the location of the mega fuse for you as well.
