    Manually engage high speed fan

    As an experiment, I would like the ability to manually trigger the high speed function of both fans. Does anyone know how to accomplish this? I think its not just jumping a relay as there are 3 relays for fan control and both low and high speed.

    Possible,.
    You can tap the high speed wire , but you need a 50Amp diode add to the originsl wire so no voltage or current back flow to Fan controller.

    Just air conditioning doesn't necessarily turn on both fans continuously. When the compressor cycles off, the fans turn off also. What is a "heatsink fan"?

    Then yes, my goal is to manually turn on both fans at their high speed.
