Hello everyone I've been trying to figure out my 4x4 System on my 2000 Expedition XLT 5.4 AWD/4x4 I recently acquired this vehicle about 3 months ago and have been trying to figure out my 4x4 problem so any help would be appreciated. So let me start out with the problem once I insert my key and turn vehicle to on position all the dash light come on as usual before starting car and noticed that non of the 4x4 lights illuminate at all however 1 of the lights is supposed to illuminate for a second before going off until 4x4 is engaged via switch however nothing happens here's what I've done
Replace light bulb in cluster for all of 4x4 lights to see if that was problem
Checked all the fuses related to 4x4 and even replaced them regardless
Checked 4x4 Switch the 2 outer wires are for the light bulb on the switch itself and the 2 inner wires are for the 4x4 they are the 2 wires that are not getting power
Had a code for a bad vss vehicle speed sensor so went ahead and replaced it and the sensors on transfer case along with shift motor and it fixed the code but still nothing no power
What so ever
I checked relay in dash also no power and went ahead and swapped them out with ones I know work and still no clicking of relays when turning 4x4 switch however if I unbolt the transfer case shift motor and manually turn transfer case into 4x4 the relays click but still no power to cluster light or switch
Also followed all the wires checking for a break or missing wire or bad ground and everything is fine
So I've pretty much replaced most of the components related to the 4x4 and am at the point where I need help from you guys
Let me know
