Troubles with Turn Signals 67 Barracuda

IS IT possible that you are hearing something else? Can you feel the flasher(s) and FEEL them click, or remove 1 or the other and confirm THAT flasher is causing the noise

Remember, you have 2---one for turn, one for hazard

But some cars have a breaker for other such as wipers, and the light switch has a breaker, or someone could have added a breaker.
