The resistor is used to select the fan operating mode. It has two spirals with a resistance of 0.23 and 0.82 Ohm. When turning the knob on the heater control panel, you can include either both spirals in the engine power supply circuit (1st speed) or a coil with a resistance of 0.23 Ohm (2nd speed) or turn on the motor directly without a resistor (3rd speed).
1. Loosen the resistor mounting screw.
2. Remove the resistor from the heater housing. If the resistor coils are burnt out, replace it.
