I have searched this, but couldn't quite find an answer for my problem. Like the title says my brake light and battery light blink with each other like their playing pong, it sucks. The batter light is on all the time, and my brake light comes on when i brake hard, and soemtimes for no reason, but never stays on long. Ive heard that it could be a bad relay, ground, mc sensor plug, rubber stopper on brake pedal. But the only thing that makes sense to me is the bad relay. I also get a buzzing noise coming from around the brake booster when i let off the gas. I replaced the battery and that light still stays on. The ebrake doesn't light doesn't really bug me, but the batt. light does and i know the alternator is fine and the belt is tight(checked voltage). Any thoughts and comments are appreciated.
