Seems that my tag has come off before I purchased the vehicle. I was wondering if anyone had a vacuum diagram for a 2001 blazer with 4wd? I found a few vacuum lines that were cut, a few that were just exposed, and a few that lead to no where. I want to get there little problems sorted before winter. I tried chiltons, but they didnt have anything.

 

No one has a vacuum diagram?

 

 

Thats a start, but how about where the 4wd vacuum lines branch off?

 

That is all you would have underhood. Vacuum diagrams are scarce for these vehicles. I have never found a good comprehensive diagram.

As referenced in plenty of other threads, the 4wd vacuum lines (you did not mention that earlier) branch off of the line to the HVAC system. There should be a T right before the firewall.
