The dashboard switch to the lower right side of the stearing column. If it's not there then you do not have 4WD.
If your Trailblazer is a 4x4 the switch should be to the left of the radio on the dash.

You don't. The system relies on an electric switch that must function properly in order to engage 4WD (and return to 2WD when desired). First, check the fuses. It could be as simple as that.
It was in front of the fuel tank up to 2004. On Later models it was placed inside the tank. I know, that sucks!

I can't provide diagrams directly, but you can find the ignition switch wiring diagram for a 2000 Chevy Silverado 2WD in the vehicle's service manual or by searching online automotive forums and repair websites. Websites like Haynes or Chilton often have detailed diagrams. Additionally, YouTube may have visual guides showing the ignition switch assembly and wiring.
