Side window seals on 2001 Accent

My 2001 Accent is running well but there is a whistling noise from the side
windows at higher speeds. Air is coming in from the top edge where the glass
meets the weather strip on both doors. The seals do not allow rain water in
but I want to reduce the wind noise. My car has roll up windows. Any ideas?

 

First, be sure the noise is coming from the windows and not the door seals.
Often, the top edge of the door sits out and allows air entry. To resolve
this issue, bend in the top of the door (unless the rest of the door needs
to be adjusted as well, in which case you should start with properly
adjusting the door). If the noise is indeed coming from the window
weather strip (window run), you may need to replace the window run.

 

Upon closer inspection, I noticed that the side glass begins to vibrate at
higher speeds and separate from the weather strip on the door. At lower
speeds the glass is snug against the seal. The door operation seems to be
normal.

 

The window seal (window run) should have a channel in it that prevents the
window from vibrating out of it. Most likely, the window run has been
deformed.

 

I solved the problem on mine by adding a tiny line of silicon behind
the seal. I was surprised to see the seal was just squeezed there
without any glue. I tought it was a mistake (they forget the glue) but
a friend had the same noise and also no glue.

I suggest you get the help of another person to reinstall the seal
rapidly before the silicon get too hard. It's not that easy to put it
back.
