Turn Signals not working

I assume you are talking about the flasher unit. If so, there is a bank of relays under the left side dash behind the fuse block. If your hazard flashers function you can turn them on to locate the specific relay. My signals did not work either and I replaced the flasher which did not fix anything. It turned out to be a bad connection on the back of the hazard switch. Pulled the connector off and put it back and the signals worked again.
