I hesitate to ask this, no offence, but are you sure it's the motor that doesn't work? Your post doesn't say if you tried testing the leads to the motor, which you can do with an extra battery or a charger. The leads are probably black/green, + to one will turn it clockways, counterclockways to the other, neg on opposite lead.
