cooling fan won't shut off
#1

The fans are controlled by the Engine Coolant Temperature sensor mounted in the coolant hose at the top front of the engine. Disconnect the electrical connector and see what happens. Fans should not run. If that cut the fans off replace the ECT sensor.
The ECT sensor provides input to the Engine Control Module which controls the radiator fan control relay module located under the front bumper, left side.
Let us know what you find.

Is this thing black, about the size of a small thin box of matches? Is it normally clipped to something or does it just dangle in the cavity behind the lower bumper cover near the intercooler radiator?

The relay is located just ahead of the left front tire in the space covered by the plastic skid pan. It is mounted to a spade connector and hangs down in the void infront of the tire.
