ok i need to know what color the vacuum line going into the vacuum actuator on the lower driver side for the hvac is my hose is black and i took it off with another a blue i believe maybe orange and have no air coming out of my defrost vent and am wondering if someone has a pic of a 93 or knows what color its spose to be

 

yes if anyone has a diagram of the vacuum lines for the vents. My dash vents dont work. I think there stuck on the Floor and Defrost. I dont hear them switch or move when I slick different settings and dont feel anything coming out of them.

 

solved my Dash vent issues, it was the vacuum tree that attaches to the back of the plenum. I must have left it off one of the few times that I took the plenum off . Now all my vents work and so does my Cruise control. Bunch of things are controlled by that one connection.
