This could be a problem with the grounds for these circuits. Check Ground # 404 and # 405. They are located in the left and right corners of the trunk. Make sure that each ground is corrosion free, clean, tight, and making good metal to metal contact. I have included the Exterior Lighting Wiring Diagram for your vehicle in the diagrams down below for reference. Please check out these grounds and get back to us with what you are able to find out.
