I need to know the routing for the vacuum line for the blend door. I can see the line off of the vaccum ball thing, and it goes as far as where the shock mounts, then appears to have been knocked off of some sort of connector or broken. It just ends there. I searched as much as I could (it is already dark here at 5:15), but could not find where this line is supposed to connect to. Does anyone know? There is another line that comes off and goes over to the engine...it is fine...it is the line next to/below that one that is disconnected.

 

I have the same problem. After searching the forums I ended here.
Can anyone answer the above question?

 

It to the same spot as the other. I'm assuming the black line is broke and the grey line is fine (going to the heater core valve).

They both enter/exit the firewall on the same spot (passenger side firewall under hvac box), you can see the other side by dropping the glove box and looking behind the recirc door actuator. Look for it in this video.
