I have a shift on the fly knob on the dash to engage 4 wheen drive. When it is turned, nothing happens. No indicator light, no sounds, no engaging. The fuses check out OK. I used to hear the click of a relay behind the dash when the switch was turned. Now there is no sound.

The switch in the dash that engages 4 wheel is probably bad. The switch turns the indicator light on, It also engages the actuator at the axle. I had the same problem with my f-150. I had the switch replaced. Everything ok now.
