That is correct, blinkers, running, flashers all work and reverse lights.

the brake light switch fuse is in the PASSENGER side of engine bay module box.

there is a small fuse block called the K40 relay module. located inside the passenger plastic module box in the engine bay.

NOT the drivers side.

here is a photo. check all the fuses see if one is blown, i will get the exact location but you might beat me too it lol.
