Component Location1. Auto light sensor2. Head lamps3. Lighting switch (Auto)4. Rear combination lamp5. BCM (Body Control Module)
DescriptionIt's a system that uses illumination sensor to automatically turn ON the tail lamp and head lamp based on the change in surrounding environment's illumination condition.
Replacement1.Disconnect the negative (-) battery terminal. 2.Remove the heater and blower assembly.(Refer to Heater - "Heater Unit") 3.Remove the evaporator core cover (A) after loosening the mounting screws.4.Pull out the evaporator temperature sensor (A) from the evaporator core.
DescriptionThe auto defogging sensor is installed on front window glass. The sensor judges and sends signal if moisture occurs to blow out wind for defogging. The air conditioner control module receives a signal from the sensor and restrains moisture and eliminates defog by the intake actuator, A/C, auto defogging actuator, blower motor rpm and mod
