I need help with the electronic shifting of the thansfer case. It doesent do nothing. I tested the votage at the switches got 2.2 volts.the switches do make. What voltage shoud it have?where is the electronic shifting module located?

Hey Man,

i think the module is on the T case itself. Im no expert on BW t cases but i think you can convert it to a manual shift set up if not i know they are fairly easy to find at bone yards.

the modual should be in the kick-panel behind the driver's side seat...

They do make what? clicking noises?

Have you tried disassembling the shifter motor and cleaning the contacts yet? That's the most common problem with these cases.

everyone thanks for the info, I was almost sure it was in the panel behind the seat.It doent make any sounds no lights on nothing.Mine had 2 v on the switches,so i tested the switches there working. I tested another bronco IIs switches the voltage was twice as high.4.99v. thats the reason i wanted to find the module, Hopefully its just a bad connection. I havent got my repair manual in yet.tracing wires is hard right now until i get the diagram.

I would pull it out and put a manual t-case in, just for this very reason. You don't want to be on the trail somewhere and have it do this.

Offrhoder4x4 · 11-09-2005, 05:54 PM

Manual case should definitely be considered if you have to start throwing money at it. I picked one up w/ shifter at a junkyard for $80...so something to think about if the part $ starts getting above $50.

In case you weren't aware of this, if you're on the trail and the elec shifter quits on you, you can pull the motor off the case and shift it with pliers.

I wrote this a few years ago, and I think you could use it!!

I've also seen a temporary setup that consisted of a rubber hose ran from the shaft where shift motor connects to the cab...twist the hose and shift. Explorer over here had a picture of one at one point.

Yeah, pull the motor off, clean it up and it'll probably work fine. 90% of the time, that is the only issue.

I tried the ideas everyone has gave,not there yet but getting closer. The switches actually looked great. not even tarnished. The plate it runs on fell out (the glue turned loose) small problem not the one im looking for. I borrowed a switch module, that didnt help. I will be glad when the repair manual gets here.

onward & foward

You might also check www.therangerstation.com , there's been several posts about the electric shift junk there lately.
The controller has a built in self-test that if fails, would tell you right away its bad.
The test NOT failing is not a guarantee its good however.

but as most have already said, a swap to a manual shift case would eliminate this headache from ever resurfacing.

Ok I gave up findiing the short. I cut the wires ,Installed a 3 position switch & A couple of leds for indicators.Thanks for the ideas.
