My point was that with the radiator fans running when I would turn on the ac switch the compressor would go on ( the fans would already be running.
If it's hot enough for AC I would assume that both radiator fans would be on. Of my two radiator fans one is controlled by an thermostat switch and the other by a lower thermostat switch ( upper and lower on the radiator) I guess I could install an over ride switch that would insure that the fan behind the condenser would turn on when the ac was turned on regardless of the thermostat switches.
