2004 Saab 9-3 Owner's Manual - Page 105

Instruments and controls The system uses four sensors Outside air temperature sensor Cabin air temperature sensor Sun sensor Blended air temperature sensors (located in the heater unit and the outer panel vent duct). The sun sensor is located centrally on the top of the fascia. Note: If the sun sensor is covered, the ACC system will not be able to regulate the cabin climate as intended, especially in strong sunshine. 105 Condensation water When the A/C compressor is on, the incoming air is dehumidified. The resulting condensation water is drained away through an outlet under the car. It is therefore perfectly normal for water to be seen dripping from this outlet when the car is parked. The warmer the ambient air and the higher the humidity, the more condensation will form.
