I have a vacuum problem (interior controls) have checked the actuators and they all work(defrost-heat- vent)all but the vent will work from the control switch lines. MY question is does anyone have a great layout of the interior vacuum routing (the aim  shows the stripe colors page 158 but after 40 years the colors are all black and the line going to the vent seems to connect to a distribution point above the heater <please don't tell me i need to pull the heater to follow the lines>. anyway i can locate the heater control line,the defrost  control line that only leaves two lines if anyone hase a picture of the vacuum lines on the switch and can tell me whitch one is the input and which is the actual live vacuum line it will save a whole heap of time and vocabulary, and oh yes what to hell do all the connections on the distribution point go to???
