Okay, so I searched for windshield noises in this forum but I could not find any relevant issues that might be the answer that I'm looking for. Driving down the 57 freeway today. I noticed a faint but noticable "humming" It appears to be coming from my windshield. The noise goes away on lower speeds. Is this normal? I thought I read somewhere in here that there might be a loose brace holding up my windshield. Any feedback would help guys. I dont want to end up getting a new windshield just incase this causes a 'stress" crack.

 

That hum should be the noise the mirrors make while passing through the air. I removed mine and the hum went away.

 

Also, the windshield wipers themselves will vibrate at higher speeds, and will make a noise...at least mine do.

 

Funny you mention the wipers. I also modded the arms so the wipers sit lower and out of my forward sight. Prolly out of the windstream also.

 

I have not heard it in my car, which has original windshield and wipers .I really doubt it's the windshield unless it's been replaced and has a gap somewhere.
If you think it's the mirrors, try folding them back against the car and see if it changes the noise. The mirrors may actually make a noise folded back, but it should be different from the first noise you are hearing.
Noises can be caused by aftermarket grilles, but you don't have one. And they can be caused by tires and road surfaces.
Things ike the dashboard and the wiper tray have also been reported to make noise. Do more searching on those.

 

Thanks guys. I will check search for more info and I'll try to see if it's my wipers or my side mirrors.
