First check, do you have turn signals on rear? Test with ign switch on. Brakes & turns share same wire, if you have turns at the rear you know the current is being delivered.

You need a circuit tester, but go to brake light switch next. It shouldn't take very long to find the culprit.

i had this problem, test the entire brake circuit with a test light, my brake switch was good, both turn signals worked but brake light current would not flow past turn signal switch, replaced turn signal switch an solved the problem
