Thread: Fan #1 always on.

  1. #1

    Default Fan #1 always on.

    Well, the handheld always shows it as on; and it is always on. The temp is set to default at 190°F-180°F. Why should this be the case? The proper wire is properly connected as well. Any ideas?

    LINK - read page 64. They operate in numerical succession. Fan #1 needs to be on before Fan #2.

    Understood. The issue I'm having is that even though the "fan on temp" for Fan #1 is 190°F, it's on at ignition regardless of operating temp. This morning, my coolant temp was 76°F and the fan was on. Got to work and the fan had not turned off; temp was 156°F. Just trying to understand why. Thanks for the links though.

    Since the 3.5" TSLCD also indicates it's always "On", I think the problem is with the programming.

    How would one go about fixing that, then?

    Change the numbers around. Just to any random value, in order to push out possible corrupted values.
