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.

Why is my brake light not working on my car?
The brake light circuit passes through the flasher circuit so the trouble may be between those points but it could be after the flasher switch also. If I was working on this I would replace the fuse with a brake light and bypass the brake switch. Then start moving wires around to see if I could locate the trouble that way.
What causes the fuse to blow on the parking light?
If there’s a short to ground on the grey wire from the BCM to either the instrument cluster or the heater control, it will blow the parking light fuse! That will cause you to waste a lot of time and money replacing the relay and BCM when those aren’t the problem.

You might be wondering, then, how to tell if a fuse is blown–an actual fuse, that is. You will see that the fuse has melted, and there might be charring on the panel. A true fuse typically consists of a piece of metal, most commonly an encased wire, that actually melts when overheated. This is what stops the fault (aka “short” or “power surge” ).
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.
What to do if your brake controller is not working?
If the brake pedal activates the brake output properly also then the problem is farther back either in the vehicle wiring or on the trailer. If either the brake pedal or the manual slide are not functioning properly you will need to test the wires going into the brake controller.
If the brake light switch is functional, you have to check for a bad electrical ground (some car models have the switch provided ground). It could happen due to a loose connection of the wire or the corrosion or damage of the wire ends.
What should I do if my light bulb keeps blowing?
