2004 Other Chevrolet Models turn signal problems

Electrical problem
2004 Other Chevrolet Models V8 Front Wheel Drive Automatic 50k miles

My turn signals do not work, left or right. The emergency flashers do work, which would eliminate broken bulbs, right? The indicators in the dash do not work either. I can hear the flasher rapidly clicking. I replaced the flasher and there was no change.
What is the next step in diagnosing this problem?
