Locating under-dash vac line
Anyone know exactly where the vac line to open the front vents on the air-conditioning are. I found the floor vent one but cant figure out where the louver and vac line for the dash vents are. I already fixed all of the lines under the hood and have a pretty strong vacuum to the "Jeep Egg" but the air still blows out the defroster. Anyway thanks for everyones help.

I found the one leading to the floor louver on the passenger side. I also found three more behind and to the right of the instrument cluster. Is that all? Also which ones behind the cluster go to what vent?

Got my air working and its COLD. Thanks for reading this post. One of the louvers was stuck and I fixed it and now the air works great.

Looks like you fixed it. But the line you are talking about is on top of the evaporator box, and you have to remove the dash to get to it. I had to replace it and was **** PIST OFF. It is a PITA.

Well mine was just a jammed louver under the dash apparently. I am thrilled that its cold and it was just some vac line work and that louver. Just in time for the scorching summertime heat here in FL.
