The switch I mentioned would be the headlight control switch. Do your headlights and fog lights work? You probably know, but there are three possible fuses to check; two in the passenger compartment panel and one in the engine compartment panel.
brake light switch on the pedal?... idk bout the dash if its not the fuse or headlight switch
