Hyundai Elantra: Heater / Auto Defoging Actuator
Description and operation
The 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 mode actuator.
