Cabin Temperature Sensor / Switch: Description and Operation

The In-Car Temperature Sensor operates in the following manner:
^ A thermistor in the in-car temperature sensor measures air temperature inside the passenger.
^ An automatic temperature control sensor hose and elbow is connected between the A/C evaporator housing and the in-car temperature sensor.
^ The automatic temperature control sensor hose and elbow takes air from the A/C evaporator housing air stream to create a suction in the in-car temperature sensor.
^ The suction draws in-vehicle air into the in-car temperature sensor and across the thermistor.
