HELP!!4x4 not working!!!!
hey guys
my name it tony...
im a new bronco owner.. I just bought a 91 silver edition/351W..Great condition.. OK. I was testing out the 4x4 and now the 4x4 does not want to disengage.. i put the tranny in Neutral and press the 4x4 button but all it does is blink but it does not turn off the light stays lite... When i press the button i hear a click coming from the computer... I dont know what it might be as i said i am a new owner of a bronco... can it be the switch, the computer, the transfer case? any input is appreciated.. thank you in advance...

The click you are hearing is the relay which should be behind the passenger side kick panel. That is a common thing to go out, and cheap/easy to replace. But first, get under the truck and you will find the little motor that engages\disengages the 4x4 on the transfer case. Give it a few "taps" with the butt end of a heavy screwdriver. (Just do't beat the hell out of it). 
That too is common to either get dirty and need cleaning or replaced. Tends to stick when dirty. But you also mention, that you go to neutral. If you have auto hubs, or if they are manuals and locked in, you only need to go into neutral when switching from 4hi to 4lo. 2hi to 4hi is ok to do on the fly but factory says under 40mph.
