The air distribution system is vacuum operated. The source is the engine. Check to see if the switchover block is operating. If it is, then there is probably a vacuum line loose. I had the same problem with the air distribution system before, the vacuum line that connects to the intake manifold had disconnected. Check to make sure that there is a vacuum source for the system first.
