I have a 96 Jeep Grand Cherokee and I need the vacuum line diagrams. The vacuum line that comes off of the transfer case behind the front driver tire became disconnected and I don't know where to route it to and when the vehicle shifts into 2nd the compression drops to zero and sometimes while driving it will just start stalling like its out of gas when it's not.

Your front end is engaged with a vacuum line . make sure the line is good. You will find it comeing off front axle.

Condensation water from air conditioner soaking front and rear passenger carpets. Where is drain located?

98 grand cherokee limited 5.2L same problem found leak not from heater box but from drain mount on firewall under the glove box not behind it. drain line should be located behind right front tire in the frame. Turn your wheels hard left look inside fender well right side towards back side. hole in frame where drain line should come out.

I have 31x10.5x15 tires on the rear and stock 15in tires on the front of a 96 Jeep Grand Cherokee. The front end is trying to lock in 4 wheel low. Is it because of the different size tires? Can I disable...

Tire size is critical on any jeep but especially so on ones with quadratrac transfer cases. If you run different size tires it will cause the fluid coupler inside the case to overheat and fail. (big$ to repair)
Don't drive it that way and get a matching set of tires on there asap!!!

Transfer case

It should be going to the nearest vacuum source. If it has come loose, look for the end of the hose. Once you have located the end, look in that general area, you should see a male end where that end of the hose can be reconnected.

My 96 jeep Grand Cherokee started blowing a bunch

It sounds like you may have blown the radiator. The transmission cooling lines go to the radiator, that's why you are seeing anti-freeze too. Don't try to drive it anymore, if the transmission is low on fluid, you will ruin it in no time, if you try to force the vehicle to go. Have it towed to a shop.

2000 jeep GC limited front axle problems

First thing to test is to see if the front driveshaft is getting engaged from the transfer case. With the vehicle in 4x4, and engine shut off, and in park, crawl under and try to turn the front driveshaft by hand. The driveshaft looks like a pipe that runs from the transfer case, located just behind the engine/transmission, to the front differential. If it rotates by hand, there is a problem with the transfer case. Some Jeeps have a vacuum actuator on the front diff that slides a collar inside the axle tube to engage it. I will watch for you findings, and you can leave me another message, and I will be happy to chat back with you on your findings.

On my 1993 Jeep Grand Cherokee the vacuum line coming off of the transfer case (quadra-trac) has come off the vacuum side (do know where it came off from) I looked around the intake, and under the air...

If it's attached to the diff housing and not to the box on the r/f axle (if you have one) it is a vent hose. Just secure it anywhere out of the way on the firewall. Don't pull it tight or when the axle moves it will fall off again!

Transfer case? Front diff? HELP!!

Sounds like a transfer case problem. But I can't verify that from here. Coupler is inside the unit on the output shaft and needs teardown to get to it.

1996 jeep grand cherokee ltd problem with transfer case because of different size tires

You should have the same size tires in the front and back. By having 2 different sizes, you are changing the gear ratios between the front diff. and rear diff. You could wipe out the t-case especially if it is full time 4wd.
