Default Brake Light Mystery

Hey im new and i own a jeep. but im trying to figure out the problem with my dad's 94 ranger. his brake lights wont turn on when he presses the pedal.. but the running lights will come on? i was thinking it was a fuse but i checked them all and they seem to be fine. did i miss something? please help.

Check the brake light switch up under the dash. Just follow the brake pedal up under the dash.

backprobe the wires going into the switch and hook them up to a multimeter. when you press the brake pedal the reading should change, if it doesn't then the switch is bad.
