No brake lights + emergency light?!

Do you know for sure that both brake lamps worked before you went in?
I personally wont go to so much effort to replace half of the switch, cancel cam. If those 2 little wires aren't mashed flat and laid just right they can distort plastic, feck up switch operation.
A whole new switch saves a lot of grief. And that needs to be a quality part. The part store switches are junk. Our member slantsixdan can hook you up with a quality part. Tighten the screws evenly to draw the switch assembly down nice and flat, good to go.
