PUSHBUTTON 4X4----- NOT ENGAGING
I have a 94 F150 with the push button 4x4. new problem just came up.
When you push the button, you can hear the relays click but the indicator light does not come on nor does it engage the front wheels.
I do see a noticable drop in the ammeter. Anyone have any knowledge on this before I tear into it???? thanks,,,,

PUSHBUTTON 4X4----- NOT ENGAGING
I had the same symptoms with my "93. Turns out the electronics that controls the electric shift motor has to read a set of switches mounted on the rear of the transfer case. If they don't get a good read the controller wont make the shift. I tapped on the round switch housing while the wife pushed the button on the dash. It was enough vibration the switches made contact and the transfer shifted. I think it was caused by not engaging the transfer often enough and the "brush" type switches sitting in the same place all the time began to loose contact. If you shift into 4 wheel once a month or so that keeps the contacts clean. Anyway, that's what I did and it's worked well since then. (knock on wood)
Good luck.
