Hi all, I found and fixed a buzzy rattle in two of my door panels that I haven't seen anyone post about. I removed a door panel and found a loose washer (I've got my finger on the washer in the picture). The interior leather bolster on the upper area of the door is held to the main door panel by several stainless bolts. Four of those bolts (2 of them off the right of the picture) also hold on the plastic cup that surrounds the interior door handle area. After removing the bolster from the door panel, you can slip in another washer to tighten up that area. After reinstalling the door panel, the buzzy rattle is gone!
