ok, so you saw where that line ran into the cars harness and intot he fire wal. inside the car take the foot cover off and pull the rug down you find that line in the wire harness, it leads to a black box in the dash. it sometimes takes a crap.
when your doing the actuators, car running, watch the vac pumps, the round things in the diagram pic in the actuator how to thread. change the air flow direction, watch for the arm to move on the round pumps there. if they dont move that box could be the reason.
if they do move, check the linkage is not broken. its mostly plastic parts and they break all on their own.
