it goes from the intake, splits out of a tee and goes to the HVAC cluster in the vehicle, goes down to the switch on the T case, form there one comes up the firewall to a vent and the other goes to the 4wd servo which is under the battery tray. if when you put it in 4 wheel drive the front end lights up on the panel down at the shifter its either the T case or the front diff and if 4 lo makes it go slow as hell like normal its the front diff

The 4wd in the 1999 Chevy blazer is electronic, you just have to push the button. If you have pushed the button and it doesn't engage, it might be a vacuum line. The lines are made of rubber and over time they melt. It costs about $25 for a new metal line. Also, the 4wd is under the battery. If you take the battery out, you might notice that a line got disconnected accidentally.

It is under the battery rack. Remove the battery and there are three bolts in the engine bay and one in the fender well.
Nope it is 4WD you can change the settings to 4WD & 2WD

We call it a horse dong, but to a partsman it would be a 4wd actuator and it is located in the front pumkin. There is a upgrade kit that can be purchased that will make it a manual engage and is generally cheaper than buying the actuator.
