Ford question don't shoot

I'm trying to help my Pastor get his 97 Ranger pickup, 4 w/5 speed, ready for inspection.
No blinkers either side, flasher light on the switch comes on but no flash from them either. All other lights work, without it blinking I can't find the flasher.
Does anyone know where it can be found or what may be causing the outage? Fuses are good
Thanks and forgive for the Ford question
Bruce
