Brake lights and hazards not working! Help

You can jumper it rather than replace it to test. If there is truly voltage on both sides of the BL switch that should power the brake lights. Most common problems of this sort are in the hazard switch, I'd assume contacts in the switch walking around.

Make a table of your TS switch colors so you know what they should do and when. You could also jumper 12V to the white brake switch wire, and with hazards off and TS switch centered, that SHOULD power the brake lights for test.
