    So, (obviously) I have a 98 Silverado, with the third door. and at 70 mph (ON THE DOT, unless its a windy day, then a little sooner) I start to hear a whistle from the passenger side. I had thought initially that it was the window on the third door, but have ruled that out. So my best guess is that the seal (or lack there of) in the doors that are causing this. Any ideas? any repairs? it seems like from the top down to about half way, I have some sort of seal, but the bottom half, there is no seal? common?

    :mechanic:

    thanks in advance for any help, ideas, or even replies!

    wipe vaseline around the weather stripping for a quick fix

    I might try that, but what about the bottom half of the door not having any seal?

    Also, you could check for wear in your door hinges. These bushings may be replaceable. An easy method I use is to open the door and grab the bottom edge,and lift a little to see if you have any freeplay. It's pretty obvious if it is solid or not.

    Hinges are good and tight, i checked about about a week ago when i threw a little white lithium grease on them. But thanks for the idea, if anyone else experiences this issue thats a good thing for them to check!
