I have a 2002 trailblazer rear wiper stopped working is it a fuse or motorized?

You can check the 30 amp fuse under the rear seat fuse # 3 LMG (lift gate module) I just diagnosed mine as a faulty wiper motor. I decided to remove it and see if i could repair the motor and i heard a clinking noise coming from the white circuit box attached to the motor, removed the cover and found a resistor that had fallen off of the circuit board. soldered back in place and the wiper works great now, saved myself $200
