Wind Noise (as if Window is Open)

I tried a search, looked through all 5 pages of search results with no aid.

When i am driving, usually over 25-30mph, there is a wind noise. almost as if my window is open. Theyre not. its coming from the rear pass door/window. I tried pushing the outside guard closer but it looks like that might be the problem. Not sure how to fix it without replacing. Ive sprayed all door seals with silicone lube.

again im not 100% sure it is the window and not the door. any idea's?

Check the rubber windstrip that runs above the doors for cracks or tears. All you need is a little break of the edge and you will get wind noise. This one is easy to change with just a few clips.

checked it all over and under lol

theres no cracks there. im trying to figure out a way to isolate where it is. Im thinking about taping the window boarder and taking a quick drive. if its gone then ill know its window. also do you think plastic wrap/food wrap would work in making the seals a little thicker so if it is a seal problem I can isolate it regardless. thatway atleast i know where the problem is

I honestly think this is your issue MyCobalt1127, check again, my car does this too, it does not need to be cracked to be leaking outside air. Mine does this and its simply worn out, it still looks good, but since its worn evenly you cannot really tell, problem likely is, its not making contact door correctly, thus leaving a small space for air to get in.


No Cost Solution:
One thing you can try, at your own risk, worked for me, is adjust the door hook, this looks like a D shaped metal ring bolted on to the door frame, you can loosen it up then pull it more inner, this will pull the door more tighter, try a little bit at a time, do go all the way at once or you could have trouble closing your door or damage your lock.

I heard you say you adjusted the guard, if you were referring to the same thing, then ignore, if not, check it out.

Thanks, Ive been meaning to give that a go. just been scared lol. if i recall correctly it uses a hex or torx screw driver, Ill give it a go tomorrow. approx how much did you move yours? i dont want to be moving it 20x by a mm if you can safely move it a few. say 2 or 3 each time

Just move it little by little, a few mm here a few mm there, you should get it eventually, it does not move much anyway.

It uses a torx fitting, not expensive., you can adjust all your doors, you will know if you have it too tight if you hear a bump/pop sound when you open the door. If this happens, just put it a little bit back. As a matter of fact I had an issue where I was getting the pop sound when opening the door, I actually had to move the thing outer rather than inner just to make the door open smoothly.

Good luck.

So I didnt get a chance to adjust the door...BUT!!

i did take a second look, while filling up gas. and it looks like the seal isnt setting properly when the door closes. it looks uneven. Ill still try tightening the close tho.
