I have a sensor between the air cleaner box and valve cover on the driver's side, looks like a blue two-connector.

As MB-Doc stated, that is the Aux Fan sensor.

Culprit?? If the A/Fans spin, high or otherwise, it's b/c they NEED TO! There's nothing wrong. Menu#18 shows how the sensor works w/ the A/C and Aux Fans.
