I would verify the issue first.
You need to go to the BCM connector and est the wires coming out f the module for power with the headlights on. You will need a set of back probes to test as the connector must be plugged in for the testing.
The diagrams I posted previously show the color wires and the connector at the module that needs to be tested. If there is no power, then the BCM is bad.
You will need a new BCM and it must be programmed by someone with the correct scan tool to upload the information into the module so everything works.
