Ok you have one of two problems here. Either the turn signal switch is bad or you have bad circuit boards in your tail lights. As long as there is not wiring problems or no one added a trailer light connector and did it wrong or something. Here is the taillight connector plate. If I was going to replace them to find out I would do one first as most parts stores will not take back electrical parts once pluged in.

Yes excatly I know what your problem is now please check the circuit boards (pictured in the previous response) in the taillights and still it could be a turn switch. See the turn signal switch is where all the power goes for the brake lights. The power goes through the turn switch then to the brake light light switch that is how the turn switch is able to interupt the brake light to make it blink when you use the turn signals. I hope this helps explain how it works. Get back to me as to what you find. To check the circuit board you may need an ohm meter if you can't find obvious signs of a short or burn on the board.
