In the US, the later 9000's all have the two stage cooling fan (not sure what year this started). It has been said that in cooler countries the fan is only single speed, but that one speed is the high speed. The two speed fan system should have two relays (picture) and two fuses in the relay box at the left front of the car. Also, the controlling temperature switch at the bottom right rear of the radiator should have three wires (single-speed fan temp switches have only two wires). Photo of the switch location.
Actually, the two stage system is a single speed motor, but the low speed thermo switch closure goes to a resistor that is connected in series with the fan motor, where-as the high speed contact connects directly to the fan motor. The resistor for the lower speed is an obvious gold-colored object that is attached to the fan shroud. Picture. If you don't see it, then you probably have the single stage system (although on earlier versions the resistor was integrated into the fan and thus was not visible).
