So I used my keypad to make sure the car was locked and my headlights that were in auto mode will not turn off unless I put them in the off position on the switch. Also, when the car is on and running the dash lights/radio/lights will not turn on in auto mode. Not sure whats going on.

Hello,

There are several fuses that run the system that need to be checked first. If everything checks out it sounds like the lighting control module is having a problem. Here is the location of the fuses, lighting module and wiring diagrams so you can see how the system works:
