Where does this vacuum line go to?
It's the gone that goes around the firewall and goes under the fuse box, after that I don't know where it leads to. I've seen some diagrams online and it says it goes to the accessories, by this I understands the A/C and stuff, but when I unplug it the A/C ports still work and switch normally. This raises two questions:
1. where does this line lead to?
2. where does the A/C get vacuum from?
Thanks.
