Breakin' wind

[ChrisF]

I have an 86 hard top GN that for one reason or another has BAD wind noise in the driver door-glass area, the car has never been hit and the weatherstipping is in great shape...I have moved the window glass all over the adjustment range, even being "too high" so as to where you have to roll the passenger window down at speed to get the driver window to "suck in" at speed or it gets stuck on the hoobie-doobie that locates the glass in it's place at the apex of it's travel....I have tried everything, is the noise coming from somewhere else?? It sounds like it's in the leading edge of the glass...the passenger door is silent and the driver door hinges, they line up perfectly.

Any help is greatly appriciated.

Thanks!!

Chris

Hoobie doobie, I don't know what that plastic tab is called either, lol. Perhaps try cutting a piece of old towel the length of the A-pillar portion of the glass and roll up the window with it between the w/strip and glass. It would isolate this area if it gets quiet. Then you can shim the back of the w/strip in that area with some house door foam insulating strips from hardware store, the kind that is 3/4" wide with sticky on one side. My window does like yours when I'm driving also, have to crack the pass window to get driver window to close properly. Either that or slow down under 50 mph and turn off the vent.

Virtually impossible to 'diagnose' by long distance and even though I had significant experience back in the '70s and '80s, not an 'expert'. Here are some thoughts (assuming you are POSITIVE about glass sealing against weatherstrip)...First, many vehicle wind noise complaints are the result of pressurized air exiting the vehicle. As mentioned before, you may want to try and determine if the noise is due to 'pressurization' of the interior. Turn blower on high with doors closed, use a length of rubber tubing as a stethescope around outside areas. If the noise(s) only occur when driving (with everything off), you may make progress by 'taping off' all 'sealed areas' around the glass, the gap between leading edge of the door and the fender and the entire A pillar molding. If this reduces the noise, remove portions of the tape in 'stages' (hopefully will isolate a problem area). Also, don't overlook the possibility of a small, unsealed opening in the front part of the door itself (inspect closely...use mirror if necessary). If you don't have a 'artificial smoke machine' these are the tips that come to mind. Just don't give up and keep on thinkin'...these problems CAN be solved.

Do you have the booklet from Kirban by Pete Serio? It has lots of details on how to align the windows and make them quiet. He also usually shows up the national get-togethers, in Bristol, Bowling Green, or Columbus, so maybe if you go to one of those, he will be there.

Thanks guys, some good ideas here. Im just sick or driving around without the driver door skin while I continue the "Trial and error" adjustment of the window glass....

I like the ideas you guys have given me, anyone else??

Thanks again!!

Chris, did you get your answers on your window? I have the door and window book by Pete Serio that gives all the adjustments and what they do. I can bring it to the next meeting if you want. I just spent the last two months adjusting both windows and replacing weatherstripping to get mine from leaking at highway speeds. Let me know.

It's called a "Blow Out Tab", at least GM used to call it that.

Paul, that would be great if I could check that book out at the next meeting, it comes highly recommended by other members on the board, and thanks again!
