Crackling/"rustling" noise in Chrysler 300M
 

While driving at freeway speeds today, I could hear an annoying noise in
our '02 Chrysler 300M -- like rustling leaves, perhaps, but loud and
constant.

Turning off the fan didn't seem to make any difference. When the car was
not moving, there was no such sound, even when I cranked the fan up to
its highest speed.

Are there ventilation ducts that could have an accumulation of dry
leaves and are independent of the HVAC controls? If so, any ideas for
dealing with the problem. And please don't tell me to pull the whole
dash apart: once was enough for a lifetime.

Or is there any other possible cause?

Possible bad wheel bearings or loose lug nuts.

It doesn't sound at all metallic. It really does sound like continuously
rustling leaves. The lug nuts aren't loose: I checked.

Maybe an exhaust shield flapping in the wind?
Loose grill component?
It may be tough to find the source.

Mouse nest in the door or glove box? Don't ask me how I know this.

An organizer for the "Million Agoraphobics March" expressed
disappointment in the turnout for last weekend's event.

It's a common problem. That's why I always keep a Burmese python under
the seat.

A Pit Bull dog might help too.

Yeah, you need the pit bull to protect you from the puthon.
