First, if there are only two wires is there any continuity between them? if not give it a whack with a small hammer and check again. Then I'd see if the sheet metal will some off and see closer where the wires go into the motor, then straighten those tabs and take the black plastic end cover off of the motor and see what you can see. Guessing there's a fuse in the windings that burned out, just take it out of the circuit, and add an inline fuse if you want.
