    Check the wiring. I believe some of the wiring is close to the exhaust manifold. Check to see if there is a fried wire.

    Doesn't the light come on the floor console after the front axle engages?

    So the front wheels lite up and not the back wheels? Have you checked to see if the front and rear drive shafts are spinning when the shifter is in 4wd?

    You can also have some one drive it slowly while you lay on the pavement and look. If both drive shafts are spinning and it doesn't engage the 4wd it could be a shift fork or worse the differential is messed up. If the front shaft is not spinning it could be the shift linkage, wiring, or your new actuator is bad. some of them are China made junk. Just some areas for you to checkout.

    I don't think that year had a transfer case control unit under the dash but i could be wrong. If someone else knows for sure about the control unit, please chime in.

    When sifting back to 2wd, does the rear wheels on the shift diagram lite up?

    Check to see if the front shaft is spinning in 4wd. That will at least tell you that the problem is before or after the drive shaft.

    Only the front part of the indicator is supposta light up. It indicates that the ft axle is engaging. It is normal. Put it 4x4 and try and turn if you get a binding its in 4x4

    Wires should lock in the front diff .

    Someone you really really trust!

    ...or duct-tape a USB webcam to your undercarriage.

    I bought a USB borescope on a 16' cable on eBay for $20 to use for stuff like this (as well as looking inside spark plug holes, transmission drain plug holes, etc).
