doin my head in.

Can someone please explain in plain English how the fcuk this can happen ?

After much dicking around managed to squeeze under the truck and have now got the transfer case motor to push the selector rod forward for 4wd.
Have confirmed that the plunger has continuity.
Up in the cab still no effing 4wd light and confirmed that it is just rear wheels being driven by the fact they just turn in the now quagmire.
No difference if using the button or pushing forward to select low ratio, all that does is make the wheels turn slower.
Flicks open the bonnet and swaps the VSV's hoses over and miracle upon miracle the magical and elusive 4wd button lights up and joy of joy I have 4wd confirmed by all 4 wheels now slowly spinning in the mud but I have traction and can move the truck.
Yes I was that excited that a little bit of wee did come out.
But the fcuking thing won't come out of 4wd unless I swap the VSV's hoses back over.
What have I done ?
I'm confused.
Help.
Please.
No seriously, help.

Sounds like one of your VSV hoses is split or broken!
You swapping them over cold put the suction on the side necessary to move the mechanism.
Or I could be talking BS!!!

The 4wd light is activated by the plunger type switch on the front diff. Have you checked that the vacuum on the vsv's is jumping from one outlet to the other when you press the 4wd button ?

At least you're on the way to fixing it now.

As Mark said, either you have a split/leaky vac hose or one of the VSVs isn't working.
I have a working pair here if you want them.


P.S. Should have done the A.D.D. delete.

Thanks for the replies guys.
Although I am probably a little bit closer to Med Ward 9 the papers haven't been signed off.Yet.

I'm still confused though.
I think that I still have the timing on the transfer case motor out of synch.
But by having the plunger on the transfer case with continuity the system thinks that the 4wd is engaged.
I can't get the transfer case motor to turn via the button.
The motor will turn if hooked up to a battery.
My head hurts

Vince how much do you want for the VSV'S ?

Does anyone have a pic of a unmolested transfer case timing disk just so I can put to bed the possibility that I have fcuked up the timing ?

I'm gonna go and sit in a darkened room.
Thanks again for the help.
