Radiator Cooling Fan Resistor: Testing and Inspection

Fig. 20 Resistor Inspection:

Fig. 21 Resistor Inspection:

1. Disconnect radiator fan motor connector, then measure resistance between terminals, Fig. 20 and 21.
2. If resistance is 0.29-0.35 ohms, resistor is satisfactory; if not, a new resistor should be installed.
