Does anyone know witch vacuum line out of the 3 is for the 4x4 light?? I had to disconnect to install a lift. And now it still engages but ligh doesn't work anymore. I know one of the lines is for the light. Can't really see in them. So if anyone knows... I'll just clean it with a piece of wire. Thanks!!

 

I'd just do this and save yourself future headaches.

This link won't work on the iPhone. What are you trying to say

 

Check it out when you get to a PC. Too complicated to explain to an iphone. That's why I posted a link in the first place.

 

Ok man. Iv never even used this on my laptop. What's the website

I might help if I understood your link issue.

In the meantime....it's the port that is sucking on the disco when you are in 4WD. I forget which one...

 

Dono the link issue. It jut says loading forever. The one sucking is the light? there's only one that will suck? out of the 3? Does it suck from the axel or the hose? Do I have to drive to make it suck or does it always suck?

 

IDLING...one line to it apples vacuum to engage it when you select 4WD. When it's actually engaged, that same vacuum is diverted to the 4WD light. The other line disengages it.

 

So witch one is for the light?

 

There's 2 right beside one another. Then one on the side

 

"..it's the port that is sucking on the disco when you are in 4WD. I forget which one..."

WHOOPS....I was backwards above.

IDLING...one line to it apples vacuum to disengage it when you select 2WD. When you switch to 4WD another "pulls it" to engage. When the thing has actually moved over, that same "engage" vacuum is then diverted back out the third port to your light.

 

Ok by your user name you have an 89. If so under your radiator bottle on the passenger side there should be a blue thing there wit a vacuum line to it that's the one you'll need to repair or clean. I forget the name but you can follow it all the way down to the axle it does turn into metal lines for a bit. The blue thing is Wat the vacuum line sucks to activate the 4x4 indicator light

 

this help

 

thanks for the diagram..so the white hose must be plugged? does any one know if it sucked the gunk into the hose or into the disco?
