Greetings!.... another 240D vacuum line mystery...the small black vac line that goes from the Vac control valve through the firewall and  stops right there about 8 inches inside the cabin...just sitting there not connected to anything.....partial diagram says ( to passenger compartment  cabin vent) Any answers welcome... Just bought this machine and am having fun chasing all the broken stuff.....finished off  the electrical gremlins... now on to the vacuum disasters........kevin
