in my ZJ doesn't switch to vents. If I had a warm garage I'd stick my head under the hood and explore a bit. Anyone have some insight on which vacuum hose operates it, so that I may investigate for blockages?

Not sure with ZJ but other vehicles I have worked on the vacuum hoses for the vents look about like 10g wire and they run into what will look like a wiring harness, should be under the dash somewhere.
They were even colored like a wire would be just fyi, look somewhere in the center probably around the middle vents. Like I said though, that is from other car type experience

I got it fingered out. The vacuum line is about 1/8 inch and goes through the firewall near where the AC lines pass through. Maybe time, heat, and being bent like it was made it break. I fixed it with a little piece of hose from Advance Auto.
