Fan Controller
- Remove the fan controller connector. See Fig 1 .
- Turn the ignition switch to the ON position. Check for battery voltage between terminals No. 1 and 3. See Fig 1 .
- Reconnect the fan controller connector and disconnect the condenser fan motor connector. See Fig 2 .
- Ensure the A/C switch is off, and start the engine and rub at idle.
- Measure voltage between the fan controller (side connector) terminals. Voltage should be 1V or less.
- Turn the A/C switch to the ON position.
- Measure the voltage between the fan controller (side connector) terminals while the fan is running. The voltage should switch between 5.6-10.8V and battery voltage.
- If the voltage does not switch as indicated, replace the fan controller.
CAUTION:
Stay clear of the fan when starts running.
