4x4 light stuck on

[Bowesmobile]

4x4 light stuck on. The selector switch is in 2wd and everytime i start the truck the solenoids in the dash make noise, the 4x4 light comes on, But the 4x4 does not engage. Just replaced the shift motor and this started happening. Im a little frustrated with it at this point and thought of getting one of these...

Update today.

I disconnected the battery. Checked fuse 17 under the hood and that was good. Now the solenoids in the dash click when I start the expedition. But the 4x4 does not engage. The light doesn't come on for 4x4 hi. If I turn the selector to A4WD the light for that comes on. When I turn it to 4x4 hi it doesn't do anything. Im trying to remember the other fuses to check. I dont know what to check next.

Check the wheel speed sensors.

Docraymund,

Why would you say to check the wheel speed sensors? Out of curiosity?

I got a little confused when I was looking for it in mine. Plus I was in a hurry and didnt have time to think. So I just rushed out and this might be my mistake.

In your opinion, could having the transfer case shift motor pinned improperly cause my 4x4 shift solenoids to click like they are trying to shift into 4 wheel drive right after my expedition is started and the drive selector switch is in 2wd mode?

By the way describing the problem, I tend more to a problem with connectors SHIFT TRANSFER CASE MOTOR. Probably the connectors are not identical. Should inspect, and make a review on the Transfer Case Shift Relays. I do not know the reason it fails to change the shift motor, but a simple shift Motor replacement should not change anything.

Very possible The relay coils are controlled from the gem 2nd print and if you look at the 3rd print the contacts from the Transfer Case Assemble provide inputs to the GEM.
