Kia Stinger CK: Heater / Auto Defoging Actuator

Description and operation
Description

Installed on the windshield glass, the auto defogging sensor judges and sends signal to blow out wind for defogging if moisture occurs. 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 mode actuator.
