I recently had a problem with my turn signals also. Sometimes they would work intermittently and sometimes not at all. The flasher (located in the steering wheel for some reason) was the first solution to the problem, but it turned out to be the socket that the flasher went in to. The flasher seems to wiggle around in it a little causing the blinkers to not work right. My dad (i'm 19 and this is my first car) did a quick fix by twisting the prongs on the flasher a little bit, and i haven't had problems with it in the past few days. Getting to the flasher isn't hard. You only have to take out 3 screws on the bottom of steering wheel. If you push in on the flasher when you turn on the turn signals you should be able to tell if that is the problem.
