97 expo won't shift into 4l or 4h

[jarnesen]

Hey, I'm new here, and I need some info. I have a '97 Eddie Expo that had 4wheel engagement motor issues, so we swapped it out for a new one. Now, it'll go into AWD, but 4H and 4L are out of the question. Could this be a switch issue, or do I need to look deeper? Any info would be greatly appreciated. With winter coming on I would kinda like to have it, just in case. Thanks in advance...

It could be a wiring issue. If the newer unit has had the shift motor changed then the wiring may have been changed.

Also could be a fuse issue.

How well can you read and understand electrcial prints?

Let me know I could send you diagrams a little later as I am away from my main computer.

I had the same issue last winter. Started a thread on it.

Fixed mine, might fix yours.

I had the same problem after I changed out my motor. I had to disconnect the battery for another issue and when I reconnected the battery it worked. Disconnect the battery for a few minutes and see if it works for you. My thinking is the computer needed to be reset.

I'll look into the fuse boxes, disconnect the battery, and let you all know what the outcome is. Thanks for all the great info.

Well ive had the same problem after for getting to put my truck in neutral so it burnt the motor up. Replaced the 4x4 motor and now it works great. Use it all the time out mudding.
