HELP!!!! does anyone have a diagram or schematic for the vacumm lines coming out of the back of a heater a/c control for a 79 t/a? i got the black one. it's the manifold source. the blue and brown ones disapear into the passenger side kick panel. that leaves the white one and a yellow one. the white one is directed in between the firewall and the defrost ducting. i can't see where it's going. the yellow one is on top of the duct work above the passenger floorboard with a broken plastic fitting in it.
