[QUOTE="montesa, post: 3306575, member: 477"] My 90 ford vents only blow from the floor. The system runs on vacuum and two actuators. I replaced and checked all the lines I can get to. There is no vacuum at the actuator under the hood near the blower motor and no vacuum at the actuator in the cab near the passengers feet. I can’t feel it at least. Are any of you guys familiar with this system? I’m assuming the issue is related to the switch in the dash and how it directs vacuum to the actuators. [/QUOTE]
