    With your A/C on it should kick in, 99% of the time its the relay, other issues is wiring or temp sender, did you replace the relay?

    No, I think the big fan switchers on at 104deg then off at 99deg, If you turn the A/C on it automatic kicks in that's if your compressor activates when on.

    The bcm controls the first fan from a signal from the ecu there's a high-speed fan controlled from the ecu directly at a higher temp.unplug the coolant sensor and turn the engine on and one fan should start followed by the 2nd fan shortly after will at least confirm if the system is working
    High fan will kick in a 111deg
