I looked through schematics and noted that the systems get power from the main relay behind the center of the dash. Also, the ECM relay fuse should be checked as well.
If you look below, I attached the portion of the schematic where I got the info. Start with the fuse. If it is good, confirm there is power to and from it.
Let me know what you find. Also, let me know if you have checked for diagnostic trouble codes.
See pics below Pic 2 shows the fuse in the under-hood fuse box to check.
