do the hazard lights work?
If not, i bet the switch is toast. I actually just replaced mine, its easier than you probably think. I ordered a new one from Rockauto several months ago that ended up being the wrong one, so if its the right one for you ill sell it to ya cheap.
The one i installed was $60 at NAPA.
