Yes, I attempted to apply 12V to both sides of the brake switch. I am not 100% sure, but I believe the top side of the switch the was the side that needed constant 12V. After doing some more searching, I am beginning to wonder if I need to replace my entire turn signal assembly or maybe my hazard switch. The brake light signal needs to travel through the turn signal and I am unsure where the failure could be there?

Ford Brake Lights
Well mine is on the floor, and Im having the same problem. They seem to light up fine with the signals, High and low side of the bulb. The Boo switch is fine, and another thing that does not work, is the hazard switch. But... if I pull the hazard switch, the turn signals wont work. So I'm assuming the hazard switch works? And the book I have says it comes from the fuse box, to the hazard switch and the boo switch, and from each switch, they have their own wire running back to the directional switch. And yes, my fuse is ok...
