Driver Seat Mode Actuator
WARNING: This page is about a different car, the 2021 Hyundai Kona. However, it is still accessible from the selected car via links, so may be relevant.
The Mode Control actuator is linked to the heater module and controlled by a driver when the driver input signals through the control panel. It consists of a actuator motor that runs the mode door, and a potentiometer that detects the door position. If a driver manipulates the panel, it ventilates the wind in the order of VENT→B/L →FLOOR.
