What to do if your brake light fuse keeps blowing out?
You’ll need a connect test light for the next step (you can get one at any auto parts store.) Turn your car’s ignition to the “on” position, grab the connect test light and attach it to a ground, like the dash or the body of the car, and gently press the tip of the tester to each of the fuse’s two ends. Now, press down lightly on the gas pedal.
Where does the brake light fuse come from?
The brake light switch is powered by the fuse and then powers the rear brake lights and third brake light also. The power also goes into the body control module to signal to unlock the shifter interlock.
What causes a fuse to blow on a breaker?
Usually, a fuse blows because the load has less resistance than expected, so more current flows than the fuse permits. The problem is not “before” the fuse, else some fuse/breaker upstream would open instead. The problem is “after” or downstream from your fuse.
Why are all three brake lights not working?
If none of your three brake lights is working, it’s doubtful that all of the individual bulbs have burned out. It’s far more likely you have an electrical system problem. It may sound complicated and expensive, but don’t worry. Odds are the electrical system trouble is nothing more than a failed brake light system fuse.
Why does my brake controller keep blowing fuse?
If there is power on the red wire before the brake pedal is pressed you have connected the red wire from the brake controller to the wrong circuit. You would then need to find the brake switch wire that has power ONLY when the brake pedal is activated.
