Re: Whirring HVAC Fan
Interesting. It happened one time to me for about 1 minute a thousand miles (a few weeks ago) but I don't recall the temperature at the time. I chalked it up to a part label of some sort that worked loose. Never happened again so I shrugged it off to what I suspected. Mine sounded more like a piece of paper hitting the fan blades.
An expert is one who knows more and more about less and less until he knows absolutely everything about nothing.
