Doug57,
I did not know your car had indash A/C, that is a totally different system. I am assuming you have A/C because you said you had vacuum hoses.
Ok, lets start over. The round thing you found is the blower assemble, and the lever you pulled that made the air go to the dash is a good start, keep that lever in that position. Now look above the blower for the A/C plenum chamber, there is a lever on it also, move it and it will change the air from the dash to the defroster.
I have attached a picture of the blower and the plenum chamber, the plenum is the part to the right with the yellow words on it, and the lever I am speaking of is circled. I hope this helps
Doug
