4x4 issues in 94 ranger STX

[jamilayers22]

Ok, 4 wheel drive stopped working, i have push button inside and manual locking hubs outside.

low range wont even come on although i can here the module working when i try to engage this.
i have tried rolling the truck backwards in nuetral, and turning off the engine, its an automatic, none of this helps with low range issues.

I did check the module to see if it is working acuratly and the fuses, both under hood and dash.
I trouble shot the module with this website, to check the conections and resistances in the wiring. http://www.therangerstation.com/tech_library/4wd_control_module.html

I got good readings accept on the speed sensor and on position 5 of the shift motor, however i dont think i had my ohm meter on a high enough grade, set it at 200. So, i can redo this if necessary.

I am wondering if the speed sensor could be the issue, and if so would it fail to engage but show that the 4x4 (regular or high light) is working. I have not had the chance to take all 4 wheels off the ground to see if the 4 wheel is actually working or not. will get to that tonight hopefully.

has anyone had the shift motor go out on them? please help me out thx.

It's so common that it's pretty much guaranteed given enough time!

Hey, so I did retest the module, 8 pin plug, with ohm meter Sry on right setting. No response from 5 and 7 pin. Is this normal? Also tested voltage to module, 5 pin dark blue and white light blue, only was reading about 6 volts... site says should read 12?

While doing this I didn't ground out anything and now tach doesn't work. Just found lose errors and had it working this morning but now it stopped again. :-( any ideas here.
