After
tuft testing my wipers on a 1991 Civic Wagon, I thought I'd move the tufts to the side windows and compare both sides. I only have a driver's side mirror. No surprise that there's a bunch of turbulence behind the mirror, but I'm wondering what's happening here on the passenger's side.
Why are the front tufts pointing up? Both sides have it, but it's much clearer on the mirrorless side.
