99 Venture Turn Signals

Turn signals work intermittently. Sometimes no problem, other times they don't work at all. No lights come on at all - outside or indicators. When they don't work, neither do the hazards. I'm thinking it's the flasher. Looked under the dash for the flasher, can't find it. Sounds like the turn signal and hazards use the same flasher, based on sound when they are working. Any ideas out there?
