funny rattling scratching noise
 

Has anyone ever had a complaint of a slight rattling scratching noise in the rear of the passenger compartment. it is intermittent and can sometimes be stopped by turning the car off and restarting. Sounds like a faint scratching sound, like radio static or something in the ventilation. hard to hear with the window open or radio or ventilation system but it can be heard clearly with windows up, radio off and ventilation off. Driving me crazy.
