The problem is not the window motor as I already stated. The window works perfectly fine, it opens and closes, it locks, it functions fine other than what seems like a "leak" coming from the window only at high speeds...

 

OP, I had the same problem on my '05. Dealer replaced my window motor for me. Unfortunately, they also scratched the 'metal' on my passenger door handle while doing it that they haven't fixed yet, but that's just because they're idiots. New window motor solved the problem.

 

Thanks for the help.
Did they give you any information on what the problem actually was?

 

check ur weather stripping around the windshield and the window. mine had started deteriorating and i am getting replaced under warranty. i was getting a very similar sound at highway speed....... hopefully this helps and doesnt end up as one of those BS threads that comes up when u search where everyone says use the search... i feel ya

 

Probably. I don't always listen very well. IIRC, it was something about the limit sensor in the motor.

 

Nah, I know what the OP is saying. At highway speeds, for some reason, the window 'drops' just a bit, like it's lazy. It goes back up with the window switch, but then it does it again. And you play this game for a couple of hours on the highway, and in the end, you want to park the car under the nearest semi truck, because it's driving you out of your ******* mind!!!

But, like I said, the window motor replacement worked for me. GL!!!

 

 

FWIW- I had this same problem with a '98 C5 Corvette (this was one of the issues listed in my Lemon Law claim). They had an Engineer from Chevy fly in to check out my car.

On a test drive, there was just enough of a crosswind to cause the condition mentioned in this thread. The "engineer's" response was,

"Oh, that's wind rush, not leaking".

I said, "I can put my hand up here and feel wind coming in".

"No, that's just a pressure change", he replied.

Car returned.

IMO- Getting the window to roll up just a few mm more would have solved the problem given that the window would have seated into the seal a bit more.
