Re: Buzzing sound at certain speeds
What can make a noise is the rubber flap in the right rear of the car, this flap can vibrate really loudly. I was in Beaners car and he had removed all the trunk carpets and panels and that thing kicked up a storm. The flap equalizes the air pressure in the car and ventilates the interior, the heater fan would not work too well if air could not escape the car as fast as the fan blows it in.
