Why does my brake light fuse keep burning out?
Why does my brake light fuse keep burning out?
The only reason a fuse will “blow” is because of a short circuit. That is a point where a wire connects directly to a ground and more current tries to pass through the wire than it is designed to handle. At that point the fuse will blow to keep the wiring from being damaged.
Why does my brake light fuse keep blowing?
Another bulb related fault occurs if the filaments in a dual filament bulb short together. If the problem is not found in the bulbs or contacts, basically any wire, ground, or component in the fused circuit is a possible cause. Failures can often be simple insofar as cause so of course check the bulbs and terminals carefully first.
Where is the fuse on the brake light?
You will get the fuse panel under the dashboard and the PDC under the hood. The brake light switch is also to be found under the dashboard and check if its plunger touches the brake pedal arm. Any problem with the fuse box and light switch will affect the brake lights. In case if the fuse is blown, change it with a new one.
What to do when your brake lights are not working?
In the situation when brake lights are not working properly, you need to make sure that the power is going through and check the fuse. If the brakes lights are turned on at the same time as turn signal lights, you need to bring it to the mechanics for a check.
Why does my brake light turn on when I push the pedal?
When the brake pedal gets pushed, a switch is triggered to send a signal to the lights out back that it’s time to turn on. Analog switches wear out over time, and they can get dirty, too, which interferes with their ability to make positive contact and transmit the right signal.
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 should I do if my brake light is not working?
Replacing a socket is as simple as snipping the old wires and splicing in the new unit, which is typically an inexpensive part to purchase. If you keep these tips in mind, most brake light problems will be easy to diagnose and fix on your own.
Can a brake light switch be replaced at the same time?
Replacing the switch is not a big job, and it’s also straightforward for your mechanic to test brake light problems like this one. If all three brake lights are out at the same time, it’s unlikely that the trio of bulbs died simultaneously.
