  1. With ignition on, A/C switch off and engine coolant temperature greater than 185°F (85°C), thermosensor completes path to ground, closing radiator fan motor relay contacts and providing current to radiator fan motor (low) but not condenser fan motor. With coolant temperature 208°F (98°C), current path will turn both radiator and condenser fans on high.
  2. With ignition on, A/C switch on and coolant temperature less than 185°F (85°C), radiator and condenser fans are on low. With coolant temperature over 185°F (85°C), radiator and condenser fans run on high.
