My AC is jacked up, it will only push air up through the defrost vents in all settings (vents, AC, floor). Anybody have any suggestion to alleviate the issue. I really appreciate the help and advice.

 

should be a tiny vacuum line that runs from the tree above the brake booster to the tree above the drier, I had mine disconnected when I was fixing my A/C and remembered about that line, as soon as I connected it, it started blowing thorgh the dash vents

 

would that tree be in the same place on a 94GT???
