Anyone have any ideas on where to start troubleshooting this? Just started today, and all that was done in between last night and today was rolling the window down and back up. The window rolls up/down perfectly fine, but today I hear a noise at highway speeds that wasn't there before. It also will periodically stop while at highway speeds for a split second.

I did a forum search and found some things on the FB/SA's, and one thread here, but had no update from OP.

 

Can you locate the source of the noise?

 

Difficult to since I'm driving when it occurs, But yesterday it was not there, and today it is. Made sure the window was up all the way, etc. Nothing looks physically out of place, but its there. I don't feel any gushes of air coming from the door handle/switches, either, or anywhere along the window seal.

 

Make sure you check for gaps in your wheel liner. I had this happen to me on a Civic years ago. One missing fastener will do it.

 

It could be from anywhere, my POS 2003 Camry has air coming in from the driver side window switch, yes window switch lol.

 

I thought about that, I felt my hand all over the door panel while it was happening, couldn't track it down. Wheel Wells are solid from what I can see, nothing missing.

 

My old daily would let air in by the door panel through the speaker grill, probably due to a worn door seal.

 

^That MIGHT be your clue to the source, if the window seal is perhaps a bit loose, or just worn out in spots, it might not be sealing 100% properly between window down/up cycles. Next time it happens on the road with the window close, crack the window open and close it. If the pitch/volume of the sound changes after each down/up cycle when closed, odds are pretty good it's the window seal.

 

I replaced the rubber door seals with new OEM stuff from Ray Crowe. That helped on my car.
