another electronic 4x4 issue

[Sloan]

alright guys so i have a 2003 ranger edge 4x4 my issue is no 4x4. I turn the 4x4 switch and nothing happens. the lights don't come on and my 4x4 doesn't engauge (neither high nor low) during start up the the lights come on still with all of the other warning. I checked the wiring out at the switch and the actuator everything looks good.

now i have a couple questions what should be my next step be

and

is there a manual transfer case for my truck and what would the major issues be in changing the transfer case?

I appreciate the suggestions

I would try cleaning the shift motor and see what that does.

As far as I know, the 1354M should bolt in place of the E; but you will need to make a hole in the floor for it.

The 2002-2003 trucks had 4x4 module problems. I've replaced quite a few of them for just dying with no warning. That would be my #1 suspect. It's behind the passenger kick panel.

I just done a lot of reading on the 4X4 control module, yes, the one behind the passenger side kick panel. As far as i know, its the only module in that location in 01-05 rangers.

Here is what I have been able to learn on this issue (because I'm going thru it too):
"PCM"= the 4X4 Power Control Module

1) if the 4Xhigh and low lamps do not test cycle after ignition = PCM issue.
2) PCM issues are caused by battery issues like impropper jumping or low voltage.
3) PCM issues have been resolved by disconnecting the connections, "wiggling" the wires and
reconnecting. This may be due to connection corrosion or the PCM just benefitted from a power reset.
4) PCMs salvaged from later year models have worked. (verify this first)
5) PCMs from salvage yards have been bought cheap.
6) most DIYers replace the the motor and switch first before looking at the PCM.
7) there many fuses and relays relating to the 4X4- check them all.
8) the majority of electric 4X4 shifting problems have been resolved at the PCM.
9) PCM part number 1L5Z-7E453-AC
10) best new PCM internet dealer price is $137.00 @ silverstateford & $140 @ partsguyed
11) this is an easy fix- don't pay somone to do this.
