Before anyone tells me to search, I already have. Shoebox's site helped me a bit but this is my problem. I was taking my brothers shift plus out of his car and instead of pulling the black wire for the shift plus I accidentally pulled the black vaccum hose from the Hvac system. As far as I can tell it goes back towards the top of the pass side firewall. I'm sure that it connects to the vaccum check valve that goes to the mode selector on the dash. The AC will not blow out of the vents. My question is how do I get to the place to connect this back to the vac check valve, or should I just bypass this and run the line through the firewall to the check valve? Should this work?

 

Nevermind, I just bypassed it and it worked.
