You're not talking about the auxiliary radiator fan, that's meant
to stay on with engine heat, are you?

No the blower under the dash, definitely not the rad fan.

just standing there looking at it,
It hadnt run since yesterday afternoon.

No, the ATC has its own set of diags. You can also step
the entire thing thru a full set of input and output checks
including stepping the fan, blend door, etc. etc. thru all
positions.

Hard to say, the ATC is what controls the blower, but I would
*think* that with the key off, it would take the power module
to make it come on with no ignition on.

Hopefully you still have the "Enter Diag Mode" where you
press and hold the two buttons on the ATC, then click one
time to display a 0 with the stick figure.
While running diags, you can go back to test select mode by
turning the temp control one click in either direction which
should get rid of the stick figure and any arrows.
From the diags mode, turn the temp **** until the desired test
is displayed in the digits. Then press A/C or RECIRC to display
the value or select an output test mode by pressing again until
the display blinks. Normally you read an output first, then hit
that button again to run the actuator test.
For number display:
No arrows= 0-99
Middle [panel] arrow = 100-199
Panel + Defrost arrow = 200-299.
Test:
1 blower control switch, A/D convertor. Display only
2 blower feedback display only
3 blower speed, can run an actuator test
4 blower high speed relay can run actuator test.
