About two months ago I bought my WRX, and like all used cars as soon as I drove it off the lot I had a problem. Whenever I hit the brakes the left turn signal decides to light up and stay on when I'm braking. When I let off the brakes the turn signal goes off. I'm not really sure where to start investigating the problem, but any leads or help would be appreciated.

It bugs the crap out of me and I assume the people driving behind me get confused when all I want to do is make left hand turns. haha
