I went to swap brake light switches yesterday as the original flickers when driving and comes on at night. Replaced with new napa switch, i let the switch dangle to make sure it worked before bolting it up. Bolted it back up and the lights cut out and would not work with the original switch or the new switch. Checked fuses and none blown. Voltage tested the car side of wiring and getting 12.5v, tested new switch as well as old switch for continuity and both are positive for continuity. At a loss at this point, anyone got ideas on whats going on?
