Stuck in 4 Wheel
'89 Bronco II with push button 4 wheel drive. I had put it in 4 wheel to go thru some rough stuff in my yard. After I was out and had stopped to put it back into 2 wheel, I accidently bumped the Low Range button. I was not moving at the time. The Low Range started blinking. I pushed the button again to get it out of low range. No good. It will not stop blinking or come out of 4 wheel. What do I need to do? This happened one time before, but after a few times of pushing the button it was OK. I have tried pushing the button in Nuetral like the manual says. I have also tried it in every gear with no success.
I need help! Any advice is appreciated.

Did you try to move the vehicle forward or backward to see if the light would quit blinking?
Have you had any prior problems with the electric shift working?
I've had no-shift problems on an 87 BII and a 93 Explorer. I had to remove the electric shift motor and clean the internals out, now both work great. This is a common problem on older machines. Let us know how it turns out.

To answer your questions. Yes, I moved the truck foward and backward. I went out on a test drive. It's stuck in 4wheel, but not in low range.
If I understand the the owners manual correctly. The blinking light means that it did not execute the shift because all of the conditions were not met.
You may be correct in saying that there is a problem with the motor.(dirty connections) But since it had been in 4 wheel for a while and had been run in 4 wheel, I would look elsewhere for the problem. The shop manual says that it will shift from high to low as long as you are traveling under 3mph when the command to shift is given.
The first thing I will do is look at the shift motor. I hope it will be that easy. I have a spare motor from a junk yard just in case I need it. If that isn't the problem, I will have to run through the diagnostics in the shop manual. I don't look forward to that.

Just a tip, go for the most obvious and easy solutions to a problem. I'd disconnect the connector at the shift motor, clean it up and try that. On this connector you squeeze the tabs and pull apart, I know that doesn't sound right, but it's true.
Actually it's usually the contacts in the shift motor housing that causes all the trouble and need cleaned, and the motor shaft/gear needs cleaned and greased.

I think that my problem has been found. It most certainly appears to be something with the shift motor and/or sensors in the motor.
I was approaching the problem with the idea that something needed a slight nudge to complete the shift. I put the truck up on my lift and tapped the motor with a soft hammer. The light immediately stopped flashing. I pushed the low range button and it shifted to high range. Pushing the 4x4 button got it out of 4 wheel.
There should be a happy ending to this story, but it isn't going to happen. I should take the motor apart and clean up the problem. Instead I'll save it for a later project when the weather forces me inside and I have the time to work on it. But before that happens it will snow, and I'll really need the truck to get around. At that time I will be forced to fix it the right way! It seems that I can never find the time to finish projects until my back is to the wall.
Thanks for the helpful advice.
