Blower Motor Resistor: Testing and Inspection

Fig 49 Blower Motor Resistor Removal/Installation:






WARNING: On vehicles equipped with air bags, refer to Air Bags And Seat Belts/air Bags before attempting any steering wheel, steering column, or instrument panel component diagnosis or service. Failure to take the proper precautions could result in accidental air bag deployment and possible personal injury.

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
