Electronic shift 4WD system won't engage in 4H or 4L?
Need some expert advice.
My electronic shift is not engaging either 4H or 4L. No LED dash light indicating such nor do I hear any sound indicating that it or is trying to engage. No clicking sounds no NOTHING??
I checked all the fuses that were related to 4x4 and all seem fine. There were some relay switches, but since I am mechanically challenged with these types of things I haven't a clue on what to do with them.
I did a search and saw some info pertaining to transfer case motors. How could I tell if it were the motor or not? Without taking it to the dealer and paying a fortune is there anything I can do first to eliminate what may or may not be causing this?
thanks in advance.

Thanks, It would seem that the shift motor would be the likely cause. Anyway to test or find out if it is for sure without just replacing it first? Hate to replace it and then find out it's not the culprit. If it were a solenoid or relay would you still hear a noise when trying to shift?

Talked to the parts guy at the local dealership and a new factory motor is $300 yikes He also mentioned a solenoid under the hood on the passenger side fender wall area near the battery. He mentioned that they have seen those go bad as well causing the same problem. $30 for the solenoid. I'll have a friend check that to see if it's getting power before I replace it. Meanwhile I'll give the motor a rap with the hammer to see if it activates again. Thanks for the ideas.

Fuses were the first thing I checked. A ok.
I rapped the motor a few times with a hammer and that seemed to do the trick. Drove the truck off pavement for awhile in 4H then switched to 4L, alternating back and forth from 2H to 4H then to 4L, then back to 2H. Everything is working fine for now. I may take the motor off and clean it up some to see if will stay working, otherwise I will just replace the motor.

When you replace it you need to seal around the circular mounting flange with hi-temp silicone. The wiring part involves removing a pin from the connector on the original shift motor and installing it in the connector of the replacement shift motor. This shift motor design has been prone to failure ever since they were introduced back in the 90's. I had one fail on my '91 explorer the same way. Evidently Ford makes good money selling the replacements so they don't seem to have any incentive to redesign it and fix the problem.

I have been watching this thread My 4 wheel drive went out after my mfg warrenty expired I bought a ford esp before the mfg warrenty expired All of the lights for 4high 4 low lite up but would not engage I took it back to my ford dealer It turned out that they had to replace a shift rod in the transfer case The bill was over $600.00 I only had to pay $100.00 I hope this fix could help other members that read this post
