did you get it back together,, I just took my gm accesory fan apart and rebuilt it,, and then the heater blower motor as well. The brass alignment balls on the shafts get corroded and they dont let the armature turn. I took this apart, drilled the brass pins out, steel wooled the shaft, electric cleaner on everyting, re-riveted the holders back in place , soldered new wires in and wala,, it works like new
