Turn Signal Problem
 

I have a turn signal problem on my 1999 Mazda Protege LX. I've looked around quite a bit and have only seen the same problem described once, with no help. The problem started a few months ago. I would use my left turn signal and when it clicked back to off, the clicking noise and bulb flashing still occurred. This would last about 10 seconds or so before it turned off. It has progressed to the point where the left turn signal is constantly on, flashing and clicking, even when I turn on the right turn signal. The fuse is not blown and I have replaced the flasher module. My only other guess is the switch itself, but I wanted to get some ideas before I drop $100 on a new stalk. Thanks
