02 ranger 4x4 edge plus 3.0. NO BRAKE LIGHTS
I replaced switch at brake pedal with no change.
I don't know what else to look for. Every other
function works ie turn and tail, and the switch has
power (i can shift out of park, etc) but they still
don't operate. all fuses are good in the entire truck.
If the rear turns work, the brake lights work. They
both use the same lamp filaments. The turn signal
switch provides the logic to determine whether brake
lights, turn signals, or combination brake and turn are
needed. The turn signal switch may be defective.
