The fan clutch can only be on/off, there is no way to vary the speed except by engine speed. If it does not fully engage to lock, and it is receiving 12V, the clutch is bad.

I can't tell what you are doing to test - do you mean with the connector attached to the clutch switch, shorting at the connector turns on the fan, but shorting below the connector (directly on the pins) does not? If so, then you have the connector pulled back too far off the pins, or the connector contacts need to be burnished clean.
