Both the headlight and doorlocks which is lift gate use the same ground behind right kick panel. That can be loose or a bad ground to the body altogether from the battery. They also use the same fuse.

Could be a fusebox, BCM, or wiring issue. Anything done to vehicle just prior to this starting to occur?

Thanks for the help gentlemen. The question posed by fixitmr has 2 answers. The battery was replaced 2 weeks ago and the ac evaporator was replaced 8 days before this started happening. The vehicle also needs a new compressor as it is only running at 50% and the intial back window latch trigger issue initially began when I turned on the ac and the compressor kicked in. It has now moved on to the door locks and the head lights.
