VIBRATION NOISE

[Hummer Kid]

Can some one tell me what this might be ? when taking off and on accelaration i hear a vibration noise coming from the glove box area. i have empty the glove box and it still comes from that area and it sounds like a buzzing vibration noise from there.

I have the same noise! Just a soft vibration, brief, only when going through about 2,000 rpm. It's definitely behind the dash somewhere. And it's driving me out of my mind.

Do either of you have an aircharger system installed? I had a very bad vibration around 900 RPMs until just recently. I found that my aircharger bracket bolt and nut, forward most on the passneger side fender well, had vibrated loose. Also, the bracket attachment to the block also was loose. Tightened both and the noise is gone. I think I will install rubber bushings when the weather calms a bit and perhaps some LokTite.

I have always had a very minor vibration in the dash but only at very high RPMs (like when passing) and this is infrequent enough to be an issue.

ah...the wonderful H3 noises! The only noise I have now is one that sounds like my windshield is about to explode when I drive 70+ mph. Wonder if I should be worried...

Just do 80MPH. That way the sound will go away

Then the windshield trim will vibrate.
