When you calibrate the Air con, it should read '0' not '1'. You obviously have a fault. If you contact a local Saab dealer they should be able to tell you what it means. Before I bought my 9000, I test drove a '92 9000 and the fan did not work at all. The delaer said that the blower motor was to be replaced before the car was sold. Don't know how expensive it is to change!
