Rattling windshield trim---that was easy!

[twinmill28]

I had my windshield replaced over a year ago, meaning that damn plastic piece has been making noise since then--I was just too lazy to see what it takes to fix. I know there are alot of posts on this topic, but I wanted to refresh for the new HUMMER owners who haven't dealt with the problem.

I was at a buddy's house today with my tool bag in the passenger seat and waiting on him, so I figured what better time to have a look at it as everything was in place---I was standing right there and my tools were right there.
There are TWO philips head screws on the door side of the trim under the top rubber door seal when the door is open. Remove those screws and pop off the trim---wow, that was easy. Once the trim is off there is some foam stuck along the length of the trim, about 18". Mine was compressed and dryed out and what I feel is the culprit for the annoying noise. With the stars really aligned in my favor, I had to go to the hardware store anyway, so I took the trim with me and asked the guy if they had that kind of foam. I replaced the old stuff with some new self stick foam and put a couple tiny pieces on a few other parts of the trim that had some kind of thick tape on it, I figured those must also be contact surfaces. I put the trim piece back on, two screws back in and door rubber back in.
It took less time than it took me to type this out----that was easy!

This story is for those guys/gals with this problem but not sure where to start to fix it. Hope it helps somebody!

I had mine replaced about 6 months ago and it has been doing it every since.. Can really tell when behind or close behind a semi for some reason. Intermittent gusts or something.. Anywho, will give your suggestion a try because it is getting old...:huh:

Its because of the A pillar moldings around the windshield.... the fix is to put a thick bead of silicon on inside of the A pillar from the top to the bottom, this will stop the air from getting in and vibrating the plastic molding. i had it done at saflite. There are some others on here who have some other fixes but this is what helped my vibrating windshield issue.

I think the fixes on the H2 and H3 might be slightly different. Either way, finding an effective way to secure the windshield trim to the windshield or A pillar is the key. I ended up using nutserts to secure mine on the H3. Less elegant, though the black screws don't really stand out, but it gives me the flexibility to easily remove the A pillars if I need to run wiring or replace the windshield.

Silicone and double-stick foam tape are the two leading solutions to this problem on the H2 and H3.

Reasons I didn't use silicone is with my luck I'd take a rock in the windshield in the next week and have to pull it all back apart, but this time be trying to clean up silicone---thus another year before it gets fixed again!
I figure the foam I put on was really spongy and will provide a nice cushion to keep it from doing it again. If I have the windshield replaced and the foam is bad, I've got a roll in the garage now and I'll just foam it up. With how quick this fix is, it encourages even a lazy guy to take care of it.
But really, I'm not sure which was worse--the deuce making that noise, or my wife bitching about it!
