The fan should turn about 1/8 of a turn every time you turn on the key.

The main test people use is what you did pulling the pressure switch on the AC will make the fan spin full speed.

The proper test is to use a bidirectional scanner like the Foxhall 510 or Foxwell 710, and then you can just command the fan on at different speeds
