The 9v motor you mention may have come from an older set, I've had one motor 
which failed, I got it from the 8479 Barcode Truck set myself, when I opened 
it up I found that the part which has the motor spindle had been chewed up 
by the metal gear driving it, and this created a hollow in the plastic where 
the motor could not engage the spindle and therefore not drive it at all, 
rendering the unit inoperative.

I'm sorry to say if this has happened to your motor internally, the only way 
to confirm it would be to take apart the motor, unfortunately this is not 
recommended as there is no way to repair this sort of damage.

If it is due to electrical fault, and the part inside the motor hasn't 
failed, I would recommend that you keep the motor intact instead, and call 
LEGO to arrange for a replacement motor unit, as later versions of this 
motor address the drive spindle problem and will be less prone to this kind 
of failure.

I don't know if you'll be asked to pay for it although it may be likely if 
the motor looks used, and isn't looking new on the outside.
