I suspect that the buzzing I am hearing from the direction of the passenger air bag is actually coming from the windshield wiper on that side. Two different passengers have said it sounds like it is coming from there and it only happens at right around 45 mph. I searched but didn't see a topic on this. I looked around the interwebz but there were lots of people saying lots of things that sounded pretty daft. What's the best solution for this?
