Why is cold air blowing out on driver side and hot air on the passenger side on Kia sedona?

The issue of cold air blowing on the driver's side and hot air on the passenger side in a Kia Sedona typically indicates a problem with the vehicle's dual-zone climate control system. This could be due to a malfunctioning blend door actuator, which controls the flow of air from the heater core and AC. If the actuator is stuck or broken, it may fail to adjust the temperature appropriately for each side. Additionally, low refrigerant levels or a blocked heater core could also contribute to this temperature imbalance.
