Blower Motor Resistor: Testing and Inspection
Fig 38 Front Blower Motor Resistor
To test the blower motor resistor, unplug the resistor wire harness connector. Each blower motor switch input terminal on the resistor must have
continuity to the resistor output terminal, which is connected to the circuit going to the blower motor. If the blower motor resistor continuity does not
check OK, replace the faulty resistor.
NOTE: The rear blower motor resistor for rear heater-only models is only available as a part of the blower motor assembly.
