Described herein is an example of an air register assembly for a vehicle heating, ventilation, and air conditioning (HVAC) system. The air register assembly has a first set and a second set of vanes aligned in mutually perpendicular directions in a housing. The second set of vanes includes a detent control vane having a detent component capable of being formed as a protrusion thereon. The air register assembly further includes a vane controller having a resilient member capable of sliding over the detent component to control a movement of the first set of vanes. The resilient member is compressed when sliding over the detent component to control the movement of the first set of vanes.
