YJ Heat Control on "Vent" setting?

Hey, hope I'm posting this right, and to the right place; newbie here.

I recently picked up a '95 TJ for my son, and we both love it. I've been fixing up a few things on it, and have a question about the heating controls.

It has no AC.

Everything works normally, but when flipping to "VENT," nothing blows.

I have some service manuals for the TJ, but nothing seems to cover the Heating lever.

I haven't had it apart yet, but I notice on a photo of the heat controls, there's a switch in behind that seems like it would be closed if the heater were put on "VENT."

(See here: http://www.eadoffroad.com/image/cach...71-500x500.jpg on upper right, this switch you can feel closing when you go to vent. What does it do?)

Are there separate fans, or something else electrical that has to take place to switch to the vent setting?

(I'm confused as to why it isn't just a vacuum thingy, and why a switch is involved...)

Any insight greatly appreciated. Defrost and Heat settings both work fine.

The vent setting is just that, a fresh air vent from the outside. There is no fan pushing or pulling the air into the cab.

Ah, this explains much. Thanks.

(I remember something similar on an old, old, car of my dad's, but haven't seen that behaviour since; new to Wrangler's, but it won't be our last! )

Np. Took me a few days when I got my YJ to figure it out as well. Welcome to the Jeep world.

Then the HVAC control head is not working correctly. Vent has no power to the blower or any other electrical device.
