so it comes from that vent area near where the wipers connect?
Seems like the physics wouldn't work since that is a horizontal surface and air traveling perpendicular to that inlet would create a vacuum in the opposite direction like blowing over the top of a straw draws liquid out the top.
At any rate it is working, I just expected an opening somewhere on the front of the car or something with a direct route to my feet.
No, actually the base of the windshield is a neutral or higher-pressure area. THAT's the theory behind cowl indiction. Otherwise, why bother. If it was a low-pressure area, it would suck air out of the carb or interior vents.
