9000 CSE V6-2962cc 3.0L DOHC (B308) (1996)
Blower Motor: Description and Operation
Current Supply
Current is supplied from fuse 6 to main fan switch 149 and on to ventilation fan switch 35. The main switch is controlled by the air distribution control
and breaks the circuit when the control is in position 0.
The fan selector switch, which controls fan motor 36 across resistor 74, can be set to four fan speeds. In position 1, the entire resistance is connected,
which gives the lowest fan speed. In position 4, the resistance is bypassed, which gives the highest fan speed.
The resistor is equipped with a fuse which blows in the case of an overload.
