ebrake light test

[N19]

thanks for replying,
I did test the switch with the buzzer on a multimeter, I'll replace the switch anyway, how can I get the roof to work. even when I first turn the key the bulb doesn't light up that's why I thought the bulb is blown I did put a wire across the plug still no light on the dash, is the brake switch a direct feed to the dash light, There is a miss fire on cylinder 6 I'd like to get into the engine compartment. please tell me how I can get the roof working or move it at least
