I can't really find much on this topic.
And I can't really find what I'm looking for in general. AND YES I have tried google.

I'm trying to find something on a window channel
The seal/channel that your window slides up and down in I think that's what it's called.
I read somewhere that it had to be bought from a dealer ship for another vehicle that's not a cavalier.
But I was curious if anyone knew of an aftermarket replacement or do I have to buy from GM?

When I'm driving I can hear air leaking in. It doesn't leak water... yet
I can put my hand up against the window and the seal and the sound stops.
So... Is there any.... creative way I can fix this. Or do I need to go to GM to buy the seals....

youre talking about the weatherstripping that goes in the door frame. pretty sure theres at least one company that makes them but i dont have a link and cant remember the name right now. but the wind noise is caused by the plastic b pillar cover breaking IIRC. go to a junkyard and you can get both. in fact, to get the stripping off you have to remove the pillar cover, but its only 3 screws so its easy. find one that has all 3 tabs intact and swap it over and see if that fixes your problem.

Alright yeah.. I looked today and all three tabs are broken on BOTH of my B pillers haha.
I'm going to call around tomorrow and hopefully I can find one or two!! Gonna have to paint them black to match the car somewhat though, Mine are painted to match.

HOLY CRAP! i just want to thank you both. now i know why there is so much wind noise when im driving, i checked mine and the top two tabs were broken i didnt realize it was such an easy fix. Going to the salvage yard tomorrow to hopefully grab one thats not broken.
