> Volvo 780 Air Conditioner Vents Not Opening

I have a volvo 780 and the air conditioning climate control unit is no longer able to open the vents into the cabin. I tried switching out the climate control unit, but I get the same results, so I know the issue is somewhere between the climate control unit and the actual vents. I've been told that the car has solenoids that open and close the events. On my old 780, the same thing happened and I was able to reach under the dashboard and put a piece of metal that held open the events (that was the 780 4 cylinder turbo model). In my 6 cylinder, I haven't been able to do the same thing and can't remember where I found the main valve to the vents. Does any one know where the main valve that opens the vents is? Or does anyone know where I can get diagrams that show how the vents are structured behind and under the dashboard?

Much thanks.
