Vacume Diagram

[Blazin00]

Anybody know where I can get a vacume diagram for a '00 Blazer?

What exactly do you need? I may be able to help without actually giving you a vacuum diagram.

I have a wistle and it sounds like its coming from under the truck. I just need to know where all the vacume lines are.

From UNDER the truck? There are 3 under there if it's a 4x4. They attach to the t-case above the front driveshaft output yoke. Only one carries vacuum all the time, that's the supply hose. Another goes to the front axle actuator under the battery, this has vacuum when the truck is in 4x4 modes. The 3rd is a vent, it vents the vacuum off the 2nd line when the t-case is switched back to 2WD. The source is on the back of the manifold or TB, the vent is right along the firewall, near the center of the truck if it's anything like my 94 was.
