Defrost Mode
WARNING: This page is about a different car, the 2001 Saab 9-3 and 2000 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
When front defrost button is pressed one time, ACC system will set fan blower motor speed to 18-amps, A/C ON (ECON OFF), air distribution to defrost position, normal temperature control, recirculated air to OFF position, heated rear window is turned ON, and AUTO goes off. If front defrost button is pressed a second time, air distribution remains in defrost position and all other functions are restored if they have not been manually changed since front defrost was initially selected.
