I am sure this has been asked before but please bear with me. I was replacing the front brakes on my 96 Jimmy this morning and noticed what looked like a vacum line hanging down by the transmission near the bell housing. Got to looking and noticed that all 3 of the lines were broke or had splits in them. Now I havent had 4 wheel since last year when I replaced the heater core. Figured it was something I had unhooked. I cant seem to find where the lines go. I pulled the 1 line from the pot on the hood and it was broke off . Not sure which 1 of the 2 that are broke it is. The other 1 just has a spot looks like it was lelted thru . Any help would be greatly appreciated. I need to know where those lines go.

 

No 4x4 probably because of no front axle engagement. Got to start somewhere. There is a vacuum switch on your t/c (drivers side) with 3 hoses. The images below show where they go.

 

One of the hose`s is a vent tube and connects to your trans dipstick tube. check there.

 

So they come off the transfer case valve if I am seeing things right? Any chance of rerouting them so this doesnt happen again?

 

As long as they go to where they're suppose to that's fine. Did you have any problems with your vent,floor,defrost,etc control switch?

 

Yep its stuck on heat and defrost. Knew it was vacum just wasnt sure where until this morning when I noticed the line hanging down. Looks like on the 1 it was melted and the others just dry rotted. Thanks for the help. Appreciate it.

 

Good luck to ya.

 

Thanks appreciate the help. This is my first Jimmy usually a Subaru guy. Thanks again.. Will let you know How I make out.

 

Want to let you all know how I made out. Sorry it took so long had a few things come up and well getting back to I guess whats going to be normal from now on. I finally had time today to get to this and am happy to say my 4 wheel drive works great. Want to say thank you for the help and diagrams. Nice thing to get done before winter thats for sure. Thanks again greatly appreciated.
