    Window track and mechanisms are likely worn..

    Especially if the door gets opened and closed by the glass..

    New gaskets may lesson the noise but likely won't fix it..

    The driver door see's the most use...

    How are the gaps like said above. Also, has the windshield been replaced recently. You want to make sure that there is no gap between the windshield W/S and the T-top.

    Also, while you are driving down the road, take your hand and push it between the a pillar W/S and the glass and see if the noise is coming from there.

    To be honest with you, the W/S on these cars is SILICONE BASED. It lasts a very very long time and rarely needs replacing unless they are torn.

    Nope, dielectric grease is what you are supposed to use to soften it up.

    That makes plenty sense to me because it looks fine. My driver window doesnt go up all the way, toward the front i can see where it is slightly open and lets water in. How can I fix that?

    You should pick up a Chiltons manual on the car, its one of the first things I buy after picking up any vehicle now. You need to remove the drivers side interior door panel to access and adjust the window stop or mounts. The key is to not break the plastic trim piece that surrounds the mechanical slide lock and door handle. Im assuming your door is aligned and closes fine.

    On T-Top cars..

    Also as the window mechanism becomes worn the glass will push out as the cockpit becomes slightly pressurised..

    This happens when you run the blower for the HVAC system and even while just driving as air is forced into the car from the cowl while driving @ highway speeds.

    My HVAC blows with enough pressure to make the window howl if it's just open a crack and not moving.

    If the window is loose it can take less than a couple of psi to push it outwards..

    Always use the door not the glass to close'em up guys..

    I know, I know, that will leave fingerprints on the paint..

    But your windows will thank you for it..

    Just my .02..

    Probably. The car could be a little out of square.

    Oh I thought you were suggesting that by softening the weather stripping up it would make it easier to remove. I'm pretty sure I shouldn't though, and I just wanna be clear on what your saying. So this will help seal any leaks in the stripping??

    Never done any of this before obviously lol.

    It helps to soft them down. It might help with the problem. Make sure you clean the excess out or you will have a mess in your windows after you put it down. Ask me how I know...

    As weather striping (gasketing) gets old, it dries out and shrinks, by applying a lubricant, it keeps the gasket supple, and swelled.
