What causes a fuse to blow on a brake light?
If the fuse is blown it could be caused by a shorted wire to ground, a melted light socket or a weak fuse. Check to see if the fuse is loose in it’s holder which will cause a bad connection. Enhance the tension on the holder terminals to correct the problem. If the fuse is okay continue down the guide.
Can a high level brake light be a fail?
As an example, if you had a high level LED light where one single LED lit up then it would be a fail because it’s obviously connected and faulty but, with the same light, if no light at all comes out, they have to assume it’s not connected and would pass (hopefully with an advise).
What to do when your brake light has no power?
This portion of the guide is to help you test for power when one, both lower or all three brake lights have no power.

Then use a test light to check the fuses for the brake light and BCM fuses and replace if any are blown.

Since the high mount brake light does not work also we will need to check several things. Check to make sure you have 12 volts across each of these fuses. Also check the violet/white wire at the brake pedal switch and see if you have 12 volts coming from it with the brake pressed. All checks out. What next?
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.
