Is the air selection control on a 2004 Dodge 1500 electric or vacuum?

The control that allows one to switch from dash delivered air to dash/floor to defrost windows is not functioning. It seems that it is "stuck" between exterior air input and inside recirculating functions and not really on either. Moving the control does nothing. Blower still blows correctly, but blowing incorrectly. Is that a vacuum controlled thing or electrical and how do I fix it???
