Answer
Hi Mathew,
The hazard switch and the turn signal switch are the only two items in the system that can apply current to the turn signal lights. Unplug the hazard switch to see if it is at fault. If not, you have a wiring problem meaning something is plugged in wrong, you need a wiring diagram to back trace the power to it's source. The turn signal switch is not powered with the key off.
