I have a 1994 Bronco that works fine in 2 wheel drive as well as 4 wheel high.It is the push button 4X4 with auto hubs up front.When you put it into 4 high then shift to neutral for "Low Range" the 4X4 light and the 4 High and Low range light all start flashes rapidly together.It actually shifts to 4 low but will never come out of it.Both times I have put it in Low Range,I have had to buy a new transfer case motor to get it out.When I put the new motor on it,I have to manually turn the transfer case to 2 wheel drive to install it.When I do that the auto 4X4 works fine again as long as I don't try to shift back to Low Range.Any ideas?
 
sounds like a bad shift solenoid or your shift actuator aint sending the signal....doubt either motor was bad
 
if you have an auto, it could be the mpls on the side of the trans. may need to be adjusted, or may need to be replaced. try to crank it in netural and see if it starts.
 
How many miles on it? Probably worn shift forks in the tcase and/or too much endplay on the planetary. That lets it shift "too" far and trips up the shift computer.
 
This is all good info,so does anyone know about installing a manual transfer from a 1990 Bronco ?It looks like the same setup to me except with a stick in the floor.Also there are different computer connections,that I am afraid would cause some detents to no release or something.Thanks.
 
There won't be any computer connections on the one from the 90... just the connection for the 4wd lights. They might plug right in, but if they don't it's no big deal. Biggest problem you'd have with a tcase from a 91 or older is that it'll have a hole in the output housing that the speedometer cable is supposed to go in... and you don't have a speedometer cable. Figure out how to cut down a speedometer cable and stick it in the hole.
 
Changing to manual will cost more and be a bigger headache than fixing your electric system.

Heres the diagnostic link for it. I've used it twice over the years with excellent results. Both times I've fixed it for free. Keep in mind, these motors are rarely "bad" or wear out. You can get them rebuilt, and in the meantime just use pliars on the shift "axle" (for lack of a better term).

The electronics can seem daunting to diagnose, but if you know how to use a basic multimeter, you'll be fine. And if you don't know how to use a multimeter, you better learn because it makes working on a car much easier.
