4WD Problems

[Stroked7.3]

So i put my front shaft back in today and went to test the 4x4 out and its not kicking in HI or LO. All the lights come on in the dash. Im wondering if the actuator is going out. It wont work in Auto or with Manually locking the hubs. BTW I have Eletronic shift on the Fly Transfer Case.

Is there a fuse anywhere that controls the actuator or is it just fried and i need a new one?

Thanks

Is the plug connected at the transfer case?

I am very interested in the solution here. I aam having a similar problem, but included is my instrument panel is not showing the 4 X 4 or LOW.

on my 99 it ended up being the plug somewhat corroded and not connecting. unplugged it cleaned all terminals and it fixed it. hope it helps.

Have a look at some of the posts that I have posted and the responses, it is under 4x4 problems. There is alot of good information there. Let me know if it does not work and I will try to forward you the posts. Hope it helps.

So I hear a click when i turn the switch to 4HI then it sounds like a pump is running bhind the glove box but yet still no 4wd with hubs locked or in auto?

is the plug clean???

[Stroked7.3]

Yes the plug was clean. I got the 4x4 to work manually by getting out and locking them. Als by replacing 1 of my hubs. Cant seem to get the auto to work though, whih means vacumm leak? Correct? Where do i heck for this?

[Bowhunter-0072]

Stroked7.3 you are right you have a vacumm leak, look at all your lines fron the front diff to the pump which should be on the passengers fender. When you turn the key on the pump will start you should be able to find where the leak is.
