My brake lights don't work. The dash does not inticate a problem. My mechanic wired in power from the power windows fuse to get power to the round brake switch at the pedal. Now the switch works in reverse. That means that when the button is depressed the brake lights go ON. When the button is not depressed the brake lights go OFF. I tried a new switch and it still does the same thing so it is not the switch. You would think that as long as the unit has power the switch would do what it was designed to do which is to cut power and connect power. The mechanic said that when he tried a switch without the vacuum (I have cruise control) it worked the way it was supposed to. We are baffled. Any help out there?
