Transfer Case Vaccum Lines
hello all! ive been all over this forum and i cant find an answer for my 97 chevy blazer ls...my problem is that theres three hoses coming off the transfer case and im not sure where one goes.the one im questioning is the line that Y"s just above the transfer case.it was just hanging there.im hoping its the vent hose.then theres the two other hoses and im not sure but i think one goes to the vaccum ball drivers side,one goes to the 4wd actuator under battery tray,then the one in question i think is the vent hose.does anyone know where i can find the link that will tell me which line comes off of what and goes to what?

You're correct - vent hose is the 3rd line. Here's a diagram. Where it says "Vent to atmosphere", that is a line that goes up under the hood and is attached up near the firewall on the passenger side (if I remember correctly).
The other two lines, you are correct, one goes to the 4WD actuator and the other one connects to a "tee" near the vacuum ball (does not go directly to it, though).

Check out this thread from the Tech Article (DIY) section:
4wd Front Axle Clicking When in 2HI - Goes Away when in 4HI/4LO
It should have a diagram showing which port is which on the vacuum switch referencing the clocking pin. I say should because I cannot view my photobucket pictures from work so I am working from memory here.

Here ya go:
The plastic alignment pin is the colored lines. So it would match up with the rubber 3-way junction thing like this (looking into it, where the black dot is the hole where the alignment pin goes into):
