Does turn signal switch control brake lights?
When we use the turn signal switch, it cancels the brake light signal, on the side selected. If it did not, the lights would stay on and not flash. A bad turn-signal switch may interrupt the brake light circuit when it should not. A broken wire to or from the switch may also cause the lower brake-lights not to work.
Why do my brake lights work intermittently?
Bad Socket. If you have a single brake light out and the bulb is good, then the next step is to check the light socket itself.
