Buzzing from dash vents ....

[Dani]

Well the dealer thought they fixed my problem. I got it back last night and took it back this morning. They checked the A pillar out and found that it was the problem. Whatever they did to it- it makes no noise now. Perhaps your problem is with the A pillar as well? The noise on my H3 started out sounding like dash vibration.

The clips that held my tweeters weren't tight and I added some padding between the lip on the clip and the back of the tweeter. Could this have been the problem?

Wow. less than a week after I picked up my H3 from the shop the first time- it is still making that annoying buzzzzzzzz/vibration noise. Guess it wasn't the A pillar after all.

Well, my problem appears (touch wood) to be fixed. Dealer isolated rattle / buzzing to the heater core. They removed the dash and the tech told me that the heater core was not properly installed and was missing insulation. They re-installed it and put in the missing insulation sections.

So far, so good. They did tell me that they drove a few more on the lot (probably because I'd been in a total of 8 days for the issue) and they did find another couple new ones that had the exact same noise.
