For the last few months, on less than smooth roads, I've noticed little annoying vibration noises coming from the dash area. I found the source to be the tabs on the A/C vents. If I pinch the tab the noise stops. Anyone else experience this problem?

Tape stops the noise somewhat, but I'm thinking there has to be a better way. Maybe a small thin shim.

Yes it does it on mine also, more so when the air is on, very annoying,

I also have this rattle. I can stop it by directing the air flow maxdown and to max the left- not ideal!

I have a center vent rattle on vin 4828. Repositioning stops it. When it really starts bothering me I'll be sticking some felt in a few select locations.

Yep. At first I thought it was behind the dash. Then I found out it was these poorly designed tabs to redirect airflow.

I have the same issue from the drivers side right vent, very annoying. If anyone comes up with effective way to solve it, please share.

Yeah, noticed it right after got her back from tint shop...however, had not used air before so before I made an *** of myself and accused them of doing something, adjusted the vent and it stopped! ...other than this, have no complaints about the C7....

I have a rattle middle of dash.....i hope its the vent

Also have the rattle from the center vent. Didn't start until we were half way across the country, and did think that it was either a dash attachment or something under the dash. Then found that adjusting the vent alleviated the rattle, so mystery solved. Glad to know ours isn't the only one.

I haven't had time to investigate and try to find a solution, so hopefully someone here will come up with a fix in the mean time.

I don't have the problem, but with he new Billy Boat Fusion exhaust, I probably won't be able to hear it if does start.

Thanks for the post !!! I haven't pinched the tabs yet but I have turned the fan speed up and down thinking something was stuck in the vent system !!! Wayne

I removed the tape from the tabs...didn't seem to work that well. Still driving me nuts.....that annoying noise and trying to find the fix.

My dash and front is rattle free but the back sides below the rear hatch
buzz and it sucks!

My center vent starts rattling after the AC has been on for a bit, seems like once the plastic gets cold it starts to rattle. When I have time i'm going to see if I can stick some felt tape someplace to make it stop.

I also have a "buzz" from somewhere in the right rear when going over bumps and the like.

I have the same problem . Re positioning the vents seems to alleviate it at times . I have stopped thinking about it .....

I discovered this on mine too. I was thinking there might be a way to inject some glue in there to freeze up the metal tab.

Take the top off? Turn up the stereo? Both good work arounds

I had a really bad rattle at low speeds coming from the dash near the windshield. Was going to take it in but before I could wife hit a massive pothole which rupture the front tire, but rattle was fixed! I will let my wife drive YOUR Vette for a nominal fee!
