Why does the fuse for my tail lights keep blowing?
A brake light fuse may keep on blowing out due to a short circuit. Short circuits are almost always the reasons why fuses get blown. In the case of your brake light fuse, a short circuit might have happened due to a bulb that may have already corroded to a point where they can easily create a short circuit.
How do you diagnose tail light problems?
Block whether it's corrosion or the junction block. Itself something's going to be bad. Now if all the lights aren't working the most likely cause is probably the brake light switch.
What fuse controls tail lights?
The tail light fuse may be located in either the fuse panel in the front passenger side of your vehicle or in the main fuse box under the hood.

What would cause a fuse to keep blowing in a car?
Your car has a short circuit.
A short in the electrical system will just cause a fuse to blow, rather than the wiring overheating or melting. A short is just a poor connection between two conductors that supply electricity, causing an electrical overload in the circuit.
Does a fuse control brake lights?
Once the fuse that controls your tail lights is identified, it can be tested using a fuse tester, which will light up if the fuse is good.

How do you check a brake light with a multimeter?
Test #1: Multimeter
All you have to do is to set your multimeter to “Ohm meter” (Ω), connect each of the two probes to the terminals of the brake light switch and check if the readings change when the plunger is ON or OFF: If the reading keeps at 1 or OL, then the brake light switch is broken.
