My heater motor has no wires coming out of it at all. Where are they suppose to come out of the motor housing? There are what looks like two electric blade connectors in cutouts of the motor housing. Since there's bullet connections for the heater on the wiring harness I suspect there should be bullet terminated wires coming out of the heater motor.
 
I took a look at my heater motor, and yes, there are supposed to be wires with bullet connectors coming out of it. I didn't see how they are connected inside the motor, but there were some rubber boots filling the hole where they came out. If you wire it back up, the trick will be finding the polarity, since the motor runs equally well in both directions. I can't remember if the fan had an arrow indicating the direction, but I remember reading that one way will have lousy airflow, and the way that has the best airflow is the right way.
