Cooling Fan Switch

Inspect/Test/Replace

Because of the variations of electric cooling fan systems, manufacturers' schematics and specifications must be consulted for troubleshooting and repairing any particular year-model car.

CAUTION
Some fan motors will start, and run, without warning even though the ignition switch may be in the OFF position. Therefore, extreme caution should be exercised when working under the hood of a vehicle equipped with an electric cooling fan.

To replace the switch:

  • Disconnect the negative battery cable.
  • Unplug the cooling fan switch.
  • Then, unscrew it.
  • Reverse the removal procedures to install the new part.
  • Connect the negative battery cable to the battery.
