Pretty much the way I described it. The car as originally designed had passive scoops on the rear quarter panels for motor cooling. Here's an example where you can clearly see the scoops. http://www.evalbum.com/2781 The manufacturer later added a bilge blower to force air from the scoops through the motor. The downstream side was ducted into an air diverter (simple plastic tube with movable doors) so it could be directed below the car, inside the car toward the passenger footwell, or toward the windshield. There were problems with the design. There wasn't much heat to begin with. The blower also didn't really produce enough pressure to get the air to the windshield with usable velocity. The air smelled bad after being run through the motor. I converted a room space heater by splitting and rewiring the elements in parallel for the car's 48 volts, and adding a DC motor for the fan. For windshield defogging, I used a hand-held hair dryer plumbed to the ducts from under the instrument panel. The heat still was inadequate, but it was definitely better than the factory heat.
