On my Toyota Previa there is a lip running up either side of the windshield. I have two theories as to it's function:
1) Drip rail to send rain up and over the car and not around the side. To keep rain off the side windows for better visibility.
2) A vortex generator to keep flow attached along the side of the car where the windshield and side pillar meet at a relatively sharp angle.
Looking up from the hood:
the air flows toward the drip rail at about a 35 degree angle.
My proposed fix if it is just a drip rail and not a vortex generator.
Any ideas?
