Power sliding door electrical plastic cover is broken. on 2005 Chrysler Town & Country

Can someone direct me to a part number for the plastic cover that protects the electrical wires to the sliding doors?

You did not mention if you have Power sliding doors and Left or Right. If you have Power sliding doors, you have a flex track which contains the wiring from the body harness to the Sliding door. The wire track part numbers are different according to your vehicles build code. See your local dealership as they will input your VIN number into the Chryslers Star Parts computer and the proper part number for your vehicle will be given.
