Fan Controller
- Remove the condenser fan motor connector. See Fig 1 .
- Start the engine and run it at idle.
- Turn the A/C switch to ON position.
- Measure the voltage between the fan controller (side connector) connector terminals. Check that the values switch between 0V, 5.6-10.8V, and battery voltage.
- If the voltage does not switch between voltages as indicated, replace the radiator fan motor and the fan controller assembly.
