routing vacuum hoses, have modified diagram...
Have 2 problems, I think they are vac lines, but dont show up on the diagram, so I moddified the diagram, hopefully someone can tell me where they go...
The circle is a canister type thing looks like its connected to the coolant hoses...
The line (broken on car) connects to the back of the plenem and connects to what I believe is the cruise control.
Do these connect together?? If not any idea as to where they go??
BTW 88 GTA 5.7

Point out what you want me to investigate ( I can't read your diagram very well) and I'll go dig around awhile. Everything's a little compressed on my car right now

That's the heater control valve. I think this line runs to the heater controls inside the car, or to a vacuum manifold related to the heater controls.

that line should run into one of the wiring harnesses at the firewall. it's the vacumn line that applys vacumn to open the heater control valve when you switch on the heater control inside the car. if it is just hanging at the end it has broken off some where. just use a small piece of rubber tubing to connect them back together

Cant seem to find it, any one know for sure on the locations for either? I guess that would explain why my heater blows around everywhere and not one location? Thanks
