This first thing we need to do is check the fuses, with the systems on and the engine off, please use this guide to check the fuses inside the car and under the hood. Here is a guide to help you.

If the fuses are good chances are the BCM is out but to be sure we should do a CAN scan which can help confirm the failure.

Here is the location of the BCM and I would get a preprogrammed unit by searching google or ebay. The BCM is located behind the glove box which will need to be removed before the BCM can be serviced. Please upload a short video in your response of the problem, so I can see what's going on :) Check out the images (below).
