Stupid 4wd

4wd won't work. I've tried the hubs in auto and lock, checked the vacume line and I can hear something engaging when I turn the 4wd knob inside. Am I missing anything else to check?

Are you sure it's not working? Have you tried high and low?

I figured it out. The vac line had a hole in way at the top where it had rubbed so auto wouldn't work and the jackwaggon that was locking the passenger side was turning it the opposite way. It was the 1st time I tried 4wd so I just assumed it was in auto on both sides but they were flip flopped.

Where is the vacuum line...? I'm having the same problem just now. Can't get 4Hi or 4Lo unless I engage the hubs manually. If I leave the hubs in AUTO, the front wheels do not drive from the switch...

It's on top of the front axle on the driver side. It'll be a small black 3/8 hose.

So here's what I know (and it's not very much):

When switching to 4WD Hi, the light comes on steady, doesn't flash but does for 4WD Low.
When switching to 4WD, there is a pump on the driver's side by the degas bottle that runs continuously for a minute or 2 then shuts off. Does the same every time you cycle the ESOF switch.
There is a distinct sliding/clunk sound from the front wheels when cycling the ESOF switch.
None of the vacuum lines look obviously damaged.
I have not checked any fuses yet.

I can still manually engage the hubs.
