It's the same wire at some point. Two possibilities. It could be your turn signal switch, or your brake light switch. To check the brake light switch, put a test light on the two terminals on that switch. One should light. If one doesn't, it's probably the fuse. If you do have power on one side, push down the brake pedal and see if you get power on the other terminal. If you do, that eliminates the brake light switch as the problem. Try that first and let us know what you find. That's two faults to look for, already.
