i know this has been asked before. I looked over older posts, but did not find it completely. I am looking for a picture of where the 3 vacuum lines coming of the heater controls connect to on the engine manifold. I checked the the 68 manual and nothing there. any help with this would be great. descriptions are good however i really need to get a visual on this.
68 barracuda vacuum lines

OEM lines have color coded stripes. I had a diagram here. Don't know if I can find it today though.
Only 1 attaches to the engine manifold vacuum port. That is vacuum supply to the controller. The other 2 go on the servo/ pod at water control valve. It is or should be on the right inner fender. Controller calls for heat, one vacuum line opens the valve. Controller calls for air, other vacuum line closes the valve.

there does not seem to be a water valve of any kind on the heater lines coming off the water pump. the just go directly to the heater core

I sounds like your missing your heater valve. Is this a factory AC car?
The 2 vacuum lines go to the diaphragm on the water control control valve.
What color are those vacuum lines?
Thank you!
you are right . it is a factory a/c
