Helpful Information/Troubleshooting Hints

1. Blower motor is energized at one switch position and not energized at another.
- Check harness and connectors between defective switch position and resistor (or blower motor in HI position).
2. Blower motor is energized only when switch is positioned in HI.
- Check resistor.
3. Blower motor speed does not represent the switch position.
- Check blower switch.
