Operation, 2-Speed Radiator Fan With A/C: Notes
WARNING: This page is about a different car, the 2001 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
The radiator fan may, depending on coolant temperature, A/C pressure, car speed and outside temperature, be run at two speeds:
- Low speed
- High speed
The radiator fan is controlled by DICE via two relays, (155) and (81).
Irrespective of the position of the ignition switch, current is supplied to the low-speed relay (155) via fuse 3 and to the high-speed relay (81) via fuse 1.
