HVAC air diverter not working?

This unit has dual zone electronic temperature control. My original problem was the blower wasn't working, so I tried replacing the power module, but to get to it you have to remove the ductwork to the floor on the passenger side. As it turns out, the problem was fixed by replacing the blower relay. But as I tried to reinstall the floor vent duct work, which is high up in the dash and not visible, I had the blower on so I could tell if the piece I was tried to fit in was over the air source. I had a strong air flow thru the piece at times but could not get it to snap in place. In that process, I may have done something (closed the flap) to the air flow diverter. Because now, the air flow is nonexistent to the floor or the other vents and changing the air flow on the controller (defrost, vents or floor) doesn't change the air flow at all. I have since removed the glove box and its internals and have a clear view of the where the vent ductwork attaches and can see two actuators that control air flow. I decided to wait for some instruction before disassembling anything else.
