Check all your bulbs. One bad bulb will make this happen.

Have you looked into your turn signal switch? They get pricey, assuming your a do-it-your-selfer, without owning a power-probe, its really hard for me to tell you which component is bad. My advice is check the flasher. There maybe 2. A turnsignal flasher, and a hazard flasher. Chances are one of the 2 are bad. Look into those before the switch. They are alot cheaper also.
