2013 Jeep Grand Cherokee - Buzzes

loud buzzing noise coming from the wiper or just inside the hood on the passenger side, noise starts at 45 mph, less than 45mph no noise.

it could be the plastic cowl where it meets the windshield. put a piece of tape there to hold it down and see if it goes away I think it is vibrating and causing the noise.

Leaves and twigs can get caught in that area too and cause wind-noises. It can get into the hvac blower cage too, and cause lots of grief. I use a shop vac to vacuum the area under the windshield of debris as part of my oil and filter change routine.
