I know there are a wealth of little rattles in the Z. It appears to be a common problem. It just so happens that this one is particularly annoying to me. It begins "buzzing" or resonating when I start the car, and is intermitent afterwards. I refuse to take it to the dealership, as the local service deptartment is less than competent. If anyone has I fix, I'll give it a shot and post a DIY with pics. If not, I'm going in as soon as my schedule allows and resolve this problem, one way or another.

This TSB addresses several different rattles. I am not sure that any of them are specific to the area you refer to, but you might want to check it out.

Does it happen when the air is off or on or both? Could something be stuck down in the vent?

Starts vibrating as soon as I turn over the engine, or not, depending on it's mood for that day. If I apply pressure to the little vents, silence. It sounds like a wood-borer bumble bee caught in his hole after you spray him. More frequent during cooler weather, so I'm guessing the plastic insert is contracting, allowing for movement. My car goes back to the shop soon for fuel system upgrades and the guys there say they can fix it. Thanks for the TSB, nice to have them in one location. I'll post up when the problem is solv-ed.

yea let us know how it goes, i get a rattle up on the front dash but i guess i got use to it.

Only rattles I have in my Z are the ones in my head!

that and the stuff in my "glovebox" that goes flying when I take corners at high speeds!

If my Z looked as nice as that Brick of yours jinxxycat, I might not complain about a rattle either. But this one gets on my last nerve and it's going down if I (or someone else) have to remove the whole dash to find it. If you ever have a falling out with the Brick, shoot me a pm and I'll cut you a check. I am truly envious.

thanks for the kind words Kshep! Hope you find that rattle so you don't have to tear your baby apart!

the BY. Too bad jinxxy got it by chance when the rest of us actually wanted one

And after dealing with one Z with a sh!tty-matic, I wouldn't do it with another</span>

Kshep,

I have the dash rattle also. Took it to the dealer and they couldn't reproduce. Go figure. Anyhow, I have determined it's the same problem you are having.

It's that vent insert to the left most part of the dash. When it is cold it rattles at start up. After a few minutes it goes away. As you say, when I apply a small amount of pressure to the insert the rattle stops.

If the isert can be easily removed I'm sure somekind of thin spongy bushing or spongy double sided tape will fix it. I jsut haven't gotten around to fixing it but I wll this winter. It gives me an excuse to sit in the car while its in the garage! Ahhhh, Ohio weather!

i have been having the rattle and it is really annoying

 

[KShep]

Both the drivers side and passenger side vents were vibrating in mine...usually during colder weather...

My shop (not the dealership) finally fixed both of them...the passenger side was more pesky for some reason. I have no clue what they did...but will find out if it would be helpful.

Yeah, it happens only when its cold on mine also. That's why I'm b!tch!n' about it now.

Any info you can provide would be helpful but don't make a big deal over it. I'll figure it out one way or another.

I had the same rattle, took it to the dealer x 3. on the 3rd time they used some insulation under the vent/pillar area similar to what is above the stick shift. have not had an issue since.
