    2016 Cascadia with the DD15.

    last night, early this morning I lost all steering wheel/column controls. I have no cruise, no jake, no turn signals, no wipers, no windshield clean spray, nothing. I do have hazards. I also lost my heater/ac controls.

    has anyone else experienced this? Is it possible all that stuff is ran through the same fuse/relay & the fuse/relay went bad?

    No. If you look at your fuse panel, there are different circuits.

    It sounds like a BCM (body control module), possibly.
