Inspection 1. Check the resistance of the ambient temperature sensor between terminals 1 and 2 whether it changes by changing the ambient temperature.
Component Location 1. Heater unit assembly Compoents 1. Mode control actuator 2.
Inspection 1. Measure the resistance between the terminals. 2. The measured resistance is not within specification, the blower resistor must be replaced. (After removing the resistor) Replacement 1.
