Whistling Sound From Windshield

I have a 2010 C300 4S. This week I noticed a whistling sound coming from the windshield when I'm going faster than 55mph. It sound like it is going from the base of the windshield towards the center. I have taped up nearly every seal around the windshield and nothing seems out of the ordinary. I have fiddled with the mirrors and wipers and found that when my wipers are paused at the top the noise goes away briefly and if I use windshield washer fluid the noise goes away for a few minutes. The only thing I could possibly think of causing this is when I slightly bent the windshield arms in slightly to try to reduce chatter. Any ideas?
Thanks You

Windshield tint? It sounds like it's the wipers to me though

Could be the trim on the side edges of the windshield. I had this happen when the right trim was loose at the top.

If you have outside air coming in from the vents, that might be what you're hearing....if the air filter is not installed right. I've seen this on a few cars.
