Put cabin-comfort control back in the driver's hands with the Standard Ignition A/C Selector Switch / A/C and Heater Selector Switch (HS-428). It drops in as a direct-fit OE replacement for the 2006 Kia Optima — see the "Vehicles it fits" section for the full engine-level fitment. This switch lets the driver select the heating and air-conditioning mode and blower settings, passing that input to the HVAC system.
If a worn or unresponsive selector switch is the cause of HVAC controls that won't change modes or fan speeds, this replaces it. Signs the original may need replacing include a switch that sticks, fails to change settings, or no longer responds when operated. Listed under both names — A/C Selector Switch and A/C and Heater Selector Switch.
