Check the fuse that is located in the fuse box on the left side of the dash.
There is a 15A fuse that is for the brake lights (see diagram below).
Test that fuse. If it is blown, replace it.
If the fuse is good, check to see if you are getting power to the fuse.
Sometimes the brake light switch needs to be adjusted in order for it to make proper contact when you press the brake pedal.
I have included the brake light switch adjustment procedure as well as replacement procedure (look below).
Please let me know of any questions.
