4-WHEEL DRIVE WONT WORK

I've been racking my brain to try and figure out what it was that he unplugged that would make the 4wd not work. I can't think of anything. I would either get a chilton repair manual (from auto store or library) or have a local mechanic look at it to see what your friend unplugged. Oh and make him pay for it!

If your Bronco ahs electronic shift transfer case rather than a manual shifter on the floor. He probably unpluged the wiring harness to the electric shift motor at the transfer case.

If it is an electric transfer case, then that's what he unplugged. Why was he messing with your truck?

i have a 1988 for bronco 2 it has a brand new shift motor 4 wheel drive i changed the module and the 4 wheel light comes on because its in 4 wheel drive but it wont shift at all is there any thing else that could be doing it thanks
