Air vents stay in open position at the floor board but won't open when changed to the console 1991 corvette. If operated by vacum i can not find vacum line.
Sorry to say but GM engineers aren`t concerned where or how they do things........if I remember right we had a vette that had the same problem and some of the vac lines were actually in the fender well.............jesus ...
