My interior lights will not shut off and red car on indicates door ajar

Hello, it sounds like one of the switches on the doors that indicates the door is open or closed is stuck in the "open" position. The only thing reasonable you can do without taking it in for inspection and repair is to ensure all door latches and switches on the door jam are lubricated properly. Open and close each door a few times and see if the lights go off. Spray lubricant on the door latch areas to free up any associated electrical switch.
