OH NO!!! When you step on your brake the turn signal runs out of blinker fluid
Seriously, i believe its a bad ground. one function cancelling the other out. the square tail lights in the back are noted for it. bulb gets corroded in the socket.
Take the left tail light lens off, and check the bulb like KIK said and go from there. Take it out and see if there is corrosion on it or the socket. if there is, mix up a paste from baking soda and water and smear it on the corrosion, then wait 5 minutes and rinse it clean.(works great for the corrosion on the battery terminals too)
Gets some dielectric grease and coat the bottom of the bulb(metal part) and re-install.
