EGY8

I just purchased a 93 hatch dx with a d16y8 swap with 60k and 110,000 on the chasis. I am a previous 99 gsr and 00 si owner which were both stolen. I really like my eg but the problem is the vents dont change from the floor and its getting hot here in seattle. Just wondering what I can do to fix it. Any info would be appreciated. Thanks in advance. And pics coming tomorrow.
