A/C troublelo

[staggerd86c-10]

Ok like i mentioned in my other post i would explain about my a/c problems. It seems like an easy fix the only this is im not sureof how to hook up the vacuum lines that go connected to the a/c to make it blow out of the dash vents instead of the floor does anyone have a diagram for this? its blowing really cold but my feet are the only thing getting cold, it blows a bit out of the dash vents but i would like it to be vice-versa blow hard from the dash and a bit down on the floor. let me know what i can do to fix this. thanks
