The turn signals in my '96 silverado went out. i've changed bulbs, fuses and the flasher and still nothing. any ideas?

Do you have power at the flasher? If you have 12 v your prob. is more than likly in the turn signal switch. Also, make sure your truck doesn't have 2 flashers,1 for turn sigs. and one for emergency flashers-yo may have changed the wrong one.
