    My 02 Expedition is not giving me floor or vent. I removed the vacuum lines to the lower vacuum actuator and it seems I am not getting enough vacuum to the lower actuator at all. I checked that I am getting vacuum to the head unit. I even had a set of vacuum distribution lines from a head unit that I used to test vacuum output. It seems like that solenoids to the lower vacuum lines do not work properly. I can manually suck on the yellow and blue hose to the lower pod and make the door move to floor. It can also hold the vacuum to the lower actuator so I know I do not have a leak of any sort. Is the solenoids a common failure on the EATC units? Can I get new solenoids bridge or do I need a whole new EATC unit?
