Check the wiring. Probably got a short. It could be a short, however, if your tail lights are illuminated, then you might rule out a short. You might also check your fuse for the brake lights. If the fuse is good, then you should check your brake light switch. It is probably a small box-like object attached to the brake pedal arm. To check the switch, you will need a circuit tester or testlight. The switch has two wires. One of the wires will be hot (have current all the time). Locate the hot lead. The other side should not be hot. Now, depress the brake and check the other side. If it is now hot, the brake light switch is good. If you have tail lights, and if the fuse is good, and the brake switch is good, then the problem may be in your turn signal. Hopefully, you have a blown fuse.
