Hello,

This sounds like a BCM failure to me but to be sure lets rung down the wiring diagrams flowing this guide:

https://www.2carpros.com/articles/how-to-check-wiring

You can do a CAN scan as well to help with the diagnosis.

Check out the diagrams (below). Please let us know what happens. If the BCM is bad you will need to get it programmed which will run about $130.00 at a shop.
