There are two things you can check on a blower when it is out of the car. 
You can spin the scroll by hand and check for stiff bearings and you can
hook it up to a 12 volt battery and spin it to check for balance and lack
of vibration and noise.  (Follow Randall's recommendation on securing the
motor as it will want to rotate on you)
