Lights/hood latch????

[0430usmc]

I've been out town for the last week and just for back. My daughter drove truck (08escalade esv) this week and said the turn signals are not working, bright beams wont come on, fog lights wont come on, cant manually turn the lights off when the truck is running, dash is saying hood is open. I assumed the hood latch sensor was dirty or going bad So I started with the hood latch and took it off and tried to clean it with rubbing alcohol, but that didn't change anything. What could be going on? Any help is appreciated. Thanks
