Anyone know what would cause the brake lights to stop working? I’ve tried to check fuses but have no diagram! Can’t find the brake light switch either.

Thanks so much!

The brake lights are powered by the "vehicle electrical system control module." There are 4 fuses that run the system, here are the wiring diagrams and the fuses to check to see if any are blown.
