2. Open the fuse box. There should be a diagram on the inside of the cover that shows you which fuse is for the brake lights.
3. Check the fuse. If the fuse is blown, replace it with a new one of the same amperage.
4. Close the fuse box and try your brake lights. They should now be working.
If replacing the fuse does not fix the problem, you may need to check the brake light switch or the wiring.
