I removed the panels and found the door is shut (lying flat) which is venting air along the floor and bypassing the overhead vents. The actuator is getting vacuum but does not actuate the door. It appears that the door is not connected to the actuator. I would say that the door attachment to the actuator shaft is missing or broken.
The door can be raised by hand to close the floor vents and open the overhead vents but when it is released it falls back into the overhead closed position.
What parts/assembliesare needed to repair this condition. Approx. Cost?
Is this system strictly A/C? Is door to change air flow to heat along the floor in the winter? (There looks like a small electrical heating coil above the door.
What are the ramifications of permanantly locking the door in the up position by installing a screw through the side of the box to prevent the door from closing?
Thanks
