Thanks everyone for suggestions, but I have checked the wires, with nothing visibly wrong. I just changed the multi function switch and the brake lights still dont work. double checked the bulb and both filaments work. Very frustrating
Cant figure why I am getting power at brake switch under brake pedal, but no power to the rear? Maybe a break in wire from brake switch to the rear. With the million wires running everywhere, doubt I will find it.
Maybe just tap into 3rd brake light and put two new brake lights in back?
Any other possible suggestions?
