You’ll need a power distribution diagram for your specific vehicle.
Being that the locks, wipers and headlights are all reacting at the same time.
It sounds like you may have a power short feeding those items
Begin by tracing the circuits to try and find a common point for all 3.
I’m not familiar with your specific vehicle and it might be a faulty BCM.
But I would suggest tracking the wiring first.
