I have no idea where they pull the vacuum for the four wheel drive. In our
(Tucson) public library they have vacuum diagrams for almost all American
cars. Check yours out. Be sure to check the reference section. You can make
copies of the pages you need.
I found the dashpot that routes the air to the floor. The shaft it operates
is broken inside the vent assembly. I have no idea how I'm going to get this
thing out of the car. Looks like the entire dash would have to come out
first. I guess I'm going to have cold feet all winter. Next time, I'll try a
foreign SUV instead of the crap Detroit is pushing on us.
