Ok...I've come across an annoying vibration.
It occurs above 65mph and sounds like it might be influenced by wind direction. I've found that it can be worse going the same speed but in a different direction on the road.
I'm unsure of the location - at first I beleived it was coming from the dash (maybe a bass/speaker issue) but soon discoved that it occured with the radio off.
I've tried pressing down on the dash while traveling above 65 when the vibration can be heard and this does not change the noise level.
I also checked to see if it was the black hood vent, as well as the hardware piece that houses the washer fluid sprayers - neither of these seemed to be the cause.
There doesn't seen to be much else except the felt liner in the engine compartment that may be the cause (I rather doubt it's the liner).
Has anyone experienced this vibration (it can be rather loud)? Any suggestions? I'd rather not have to take it in so soon to get it pulled apart for the diagnosis.

Fixing it myself was a personal choice - mostly due to the fact that I'm not ready for the H3 to spend the day at the dealership....only to quite possibly be dissastified when I pick it up....
But I have to agree with you.....

Do you have the roof marker lights? I added them tonight and got the wind between 60-70 MPH. I found in other posts that others are having the same problem after they got the marker lights also.

I had a similar one, check the clear lens on the guages. I did and it stopped.
Let us know

ok - it's not the plastic covering over the guages.
I'm positive it's coming from the outside. To be more specific it can be felt in the windshield which leads me back to the piece of hardware that houses the windshield wiper fluid sprayers.
The greatest noise comes from the passenger side just to the right of the windshield wiper pivot point.
That's about where I'm at. I do know that the vibration as well as the noise increases (gets louder) as I increase my speed (up to 80mph).
Any other suggestions would be greatly appreciated.

Well this morning I ran a strip of black electrical tape along the bottom edge of the foor marker lights where it meets the windshield. I then drove down the highway at various speed where I noticed the noise. It seems like the tape fixed the problem 100%. No more noise! The best part is that if you take your time installing the tape you cant even see it, it blends right in! Give it a try and I bet you wont get your noise anymore either!

LOBO
iF YOU CALL Hummer of Novi Michigan they can tell you what to do. They did a super job on mine a month ago and I have been on the HWY several times no noise.
There are a few things to do to correct this. I did not use door edge guard to fix it either.

Lobo, where in Texas are you? Who is your dealer?
The way a dealer would probably fix it, is to put a piece of double sided tape underneath the roof lamp panel, just under the front part of it. A peice of tape on the outside will fix it also, but this way you can't see it.

On some of the plastic roof rails My H3 was missing some clips and was rattling. I thought it was from the door but the dealer was able to track it to the plastic rails on the roof. Check into that...

A little disapointing that we should have to be fixing this problems ourselfs, wheres the quality that GM is so in our face about.

Double sided tape makes since. Because I would rather not see it. Hewlett Hummer in Georgetown...haven't called them yet...thought I'd gather some information first.
Thanks

I do have the roof marker lights. I'll be sure to check them, however I feel really sure that the vibration is coming from air flow up through the seal between the hardware housing the windshield wiper fluid sprayers and the windshield.
Anyway - still testing to rule that out. Hope to know more soon - I'll keep it posted.

Well officially my vibration was caused by the roof marker lights.
With suggestions from H3Lady and Hummer of Novi, I popped the plastic caps and unscrewed the screws to find that my weather stripping was to thin (not doing it's job).
With new weather stripping from Home Depot 1/4 inch thick by 3/4 inch wide single sided adhesive (foam - easy to compress) the vibration is gone.
I placed the new weather stripping about 1/4 in back from the front edge of the roof marker lights on the underside (adhesive upward), tightened the screws back down and I was done.
At each end the original weather stripping has double sided adhesive for roughly 6 inches. I peeled mine off but ended up leaving the center area and applied the new weather stipping over the top of the old.
A test drive later and no vibration - and I didn't have to leave it at the dealership all day.... : )
Actually really easy and it doesn't look any different from before - the screws are torx though size 25.

It is my roof marker lights (Thanks!). Is it possible to tighten them?
What do you think the dealership would do to fix the problem?

It's not the roof rails either. Thanks for the suggestion though.
Any other thoughts anyone?
Didn't have a chance to trouble shoot today - hope to get back on it tomorrow.
