This sounds like you could be having a problem with your vehicle's Body Control Module (BCM). In the diagrams down below I have included instructions from the vehicle manufacturer on the removal and installation of your vehicle's BCM. Please go through this guide and get back to us with what you find out. The BCM will need to be reconfigured afterwards and will require special tools to do this. We have the instructions for how to do this and can send them right over to you if you wish.
