    You're welcome. Be careful reflashing the ECU firmware (Link). Save your Global Folder on your laptop. Don't lose battery power, disconnect, or in any way interrupt the firmware reflashing process. You may want to try completely disconnecting the battery for 20 minutes first.
    May God's grace bless you in the Lord Jesus Christ.

    No luck after reflashing ECU. I also lowered the setpoint, and the fan came on as it should. I turned off the engine and let it cool for an hour, then restarted the engine and fan would not come on at the setpoint again. It would not even come on when I turned key-on again, like it did before. I could here it start to come on, then go off, and not stay on no matter what I did. I'm going to check the voltage to the relays tonight, to see if the relays are malfunctioning or the ECU is not keeping the signal turned on.

    Yes, that seems like a wiring problem. Are you sure you're pinned in the correct connector cavity (number)?

    Problem solved! Looks like I did not plug the connector to the fans all the way in, when I re-installed the radiator & fans. Found it when I was checking the voltages. In the end, it was easy to make a whole new Global Folder, and copy over everything.

    Good diagnostic work. I knew you'd find the problem. Thanks for updating this thread.
