Only hot air from the AC system
On Saab 9000 the AC system might get stuck, resulting in a constant hot air flow. This can in many cases get resolved through a simple reset and calibration of the AC system.
To reset and calibrate the system in the Saab 9000:
- Turn on the ignition
- Hold both AUTO and OFF on the ACC device.
- Wait and allow the unit to work through the calibration. You will hear how all the dampers are opened and closed.
Check if the cool air works.
