Abstract
A rotatable driver comprising a Geneva type wheel is operated by a turning knob associated with climate designations on a mounting dashboard panel. The driver has drive pins that engage slots in tangential movement in driven links connected to push-pull cables. These cables in turn are connected to control doors in air ducts in vehicle climate control systems. The driver includes a wall segment selectively engageable with the driven links to serve as a stop such that upon driving movement of one of the driven links the other driven link is held stationary. One of the driven links has a cam edge that actuates an electric switch for an air conditioning unit on the vehicle in selected positions of the driven link. A directional air flow lever has an axis of rotation in alignment with the axis of rotation of the rotatable driver and operative between the turning knob and the mounting panel.
