The engine cooling fans do not operate at elevated coolant temperature levels. To run the fans I have to switch the climate control to A/C to bring the temperature down. If I disconnect the coolant temperature sensor on the engine block the fans will run regardless of the coolant temperature. Is this an ECM problem, if so how can I cure it?The fans don't run even when the temperature gauge is in the 'red' zone.
