Question TURN SIGNAL PROBLEM

I have a 67 F-100.The problem is when you turn on either blinker the brake light goes out instead of flashing.I have replaced the turn signal flasher,and the emergency flasher.The emergency flashers do work.Any help will be appreciated.I have been reading schematics and tracing wires for four days.Thanks

After being through this with while towing trailers out of state this sounds like your turn signal switch has given up in this life.

308 FYI, The brakes & flasher share the same wire from the front & bulb filament. So when brakes are applied the t signal is actually turning the light off making it blink.


Hope I didn't fuse you.
