It sounds like it could be a fuse, relay, or the flasher. Check you fuse panel for an open fuse and thump all relays in the power distribution panel. Look under the dash for a small can shaped or square device with two or three wires. This would be the flasher. Some times you can thump a flasher or relay and they will start working, at least for a little while.
Hope this helps
