The interior driver door handle broke away inside the door where the door latch cable is attached. I cannot open the door from the inside. Apparently you cannot buy the interior driver door handle separately but must get the entire door panel. On top of that auto suppliers have discontinued stocking the door panel. I've included a picture to show the LTZ setup and color scheme of the door panel. The exterior of the vehicle is dark red. Can anyone recommend the best strategy to find one of these door panels?
