Unknown driver message turned on

My friend as is a single mother of four. The vehicle listed above was 150,000 miles. She says has been a great car but recently it has died on her twice which left her stranded. After using it every day all of a sudden, she gets in it, and it says unknown driver and makes a clicking sound when she starts to turn the motor on. When I looked it up and checked and checked the first couple grounds, I got it to crank but no power windows power locks or radio to come on or the A/C. I got to start and run every time I change the ignition switch and pulled out the steering wheel lock because it was getting really hot to the touch, but even though it’s running the windows won’t roll down, the locks don’t work, radio Reza comes on. I’ll check the wiring harness in it in the back liftgate backgrounds on by the battery and I haven’t seen any wires. I’ve changed a couple of the grounds in the engine compartment and checked all fuses, but still nothing. I need help. Thank you
