ok, some probably will disagree with this BUT, i had the same problem with my charger, brake lights worked then they quit. i traced every wire,replaced the switch and checked for hots and nots through the circuit and established a new ground ,still nothing. at the time ,the hazzards worked to. the emergency flasher on MY circuit is also on my brake light circuit. when i went to check my flashers, it blew out the relay and thus the brake light circuit was interrupted at the same time. i chased this demon for two days.as soon as changed my flasher relay ,WABAMM brake lights. just something to check.
