This could be a problem with your vehicle's Body Control Module (BCM). In the diagrams down below I have included your vehicle's exterior lighting wiring diagram as well as the location and removal and installation of the BCM as well as reprogramming directions in the diagrams down below. Please go through these guides and get back to us with what you are able to find out.
Thanks,
