2005 boxster s - buzzing sound at 3k?

[whttkrasst]

I too have a buzzy rattle at certain RPMs. But, it's at all temps, and it's coming from the front, like inside the dash on the right side. I've emptied the glovebox, figuring something was rattling in there, tried with cupholders open and closed. It sounds like what it would sound like if the cupholders were rattling. I'll have it checked out soon.
