Does not engage 4x when I push the buttons. The amber led on the 2wd is faded most of the time and other times is normal brightness. Many times the led on the 2wd button does not even light.
When I push any selection the amber led will flash on/off on that selection with no transfer case engagement and then revert back to the
2wd mode.Where can I start?

First place to start would be to see if there are any relevant codes. When the light flashes on/off and then reverts back to 2WD....it's telling you that it has attempted to shift but for whatever reason cannot finish the shift. It might be that the encoder motor physically is not able to shift the t/case, it might be that the front axle is not engaging (though you usually see the 4WD light flash continuously and not revert back to the 2WD position).
Unfortunately...it makes diagnosis so much easier on these vehicles if you have a scan tool.
