I have a 2001 focus. The right brake light will not work. I have replaced the bulb and nothing. I checked the power to the socket and had now power. I replaced the wire harness to the brake lights and now still no power to the right brake light?? I'm at a loss any ideas? All the other lights work.

Test for ground, harness to ground connection may not be good.
