Default Re: Buzzing from dash vents ....

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.
