Title: Brake lights not working right all of a sudden

So my brake lights all of a sudden are only lighting up when I have the headlights on. Threw a new brake light switch on and no reaction ideas?

Found it it was the hazard light fuse. Apparently my stop lights run off of it as well.

Hey,
Dont know if you solved your problem but I found on my truck there is a clip under the dash on the steering column. Connections were oxidized. You could try that.
