2hi, 4hi, 4lo Switch not working

[gf999111]

On my 1997 4*4 5.7L the switches for 4*4 are not working.
There are no lights on any of the switches on.. They are all off
Pushing any of the buttons does nothing

They where working just find yesterday .. so this just happened all of a sudden

I checked the fuses in the fuse box .. all seemed okay .. possible I might have missed one ..

Anything else I should check ...

It sounds like a fuse.

With tranny in neutral, can you tell if your trucks transfer case is shifting when you push a button? If its not its likely the fuse that goes to the controls.

Its also possibly the servo that takes the signal from buttons and moves the lever on your transfer case has gone bad but it should still indicate the position that the transfer case is sitting at if thats the case.
