Smoking usually indicates a direct short. In this case, if the wiring were shorted, you would have smoking wires without the motor. If your wiring is not put together and what is suppose to be a ground wire has power to it, then it could cause the smoking condition. Check each of your wires for power and check that against the wiring diagram. If you don't have a wiring diagram, let us know and we will help with that. If you have power on a wire you are not suppose to, then you'll know why it was smoking. If the wiper motor was previously worked on, they could have done something internally there as well that would ground a power circuit. Did you blow any fuses when this happened? I would guess yes, so check that out. I am guessing it was the motor, but I would check it out so you don't have to buy another one before I hooked it up.
