I'm pretty sure if I turn my key to the on position (short of cranking), that the engine fan will come on; normal.

If you did not turn off the fan before shutting off the engine, the fan will run again by just inserting the key and turn it to position II.

its when you DONT ever hear the driver side fan there is a problem
often the temp sensor at radiator goes bad and no cooling fan
or air bubble after cooling system work or leaking water pump can all cause the sensor to be fooled and the fan not run

It needs to operate to keep that magic 2 clicks below half temp and should come on and off when you are sitting in traffic
