DESCRIPTION





Some customers may complain about a buzzing noise from the upper part of the front door panel when the volume of the audio system is loud. Due to the loud volume, both front door trim and body panel vibrate causing the rib molded on the upper part of the front door trim to interfere with the body panel, which causes the noise. The rib is now eliminated from the front door panel.
