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?
