Sounds like you need a new turn signal switch. And a new flasher relay, just in case your old one got overused! Those little flasher relay cylinders were real cheap back in the day, about $2. It's under the dash around the steering column, probably in a little metal clip (yea, real metal). Don't confuse it with the hazards flasher, both look the same. You can hear and feel the turn blinker flasher when it is doing its thing, and same with the hazards flasher, if you want to check. The clicking is the make and break contact of the circuit to cause a blinking bulb.
The reason I say you need a new turn signal switch is because the brake light signal wire is routed through the turn signal switch before it goes to the rear brake light bulbs. It is inside the turn signal switch that the brakes and rear turn signal lights are made to share the same filaments inside the bulbs. The brake lights don't pass through the flasher, but somehow your turn switch is sending power to the flasher. If the wiring under your dash has not been radically altered, really messed up, then your turn signal switch has got infected with a malware virus: it is worn out and needs replacing. Good luck with that old piece of iron, Greg.
heck power on both sides of brake light switch with pedal depressed.if power on 1 side only replace brake light switch.if no power to brake light switch check turn signal switch.
There is a conector box on the left side of your steering wheel on the colum loosen it and check your wires I bet when you just loosen the block they will start working,I hope this helps you
