interior /overhead light will not turn off.

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. If the doors are closed, interior manual light switch is turned "off" and the light remains on, then it is likely that the vehicle thinks that a door remains open. Give the vehicle 10-20 seconds for the lights to go off (often times, there is a timer that allows the lights to stay on a short time - via a setting...) and if they stay on, then it will be important to check each door, finding the door switch for each, and see if the switches are electrically stuck. You can try penetrating oil or even open and close each door several times to see if it makes a difference. Or, you can get the vehicle to a technician with proper diagnostic tools and have them actually see which door is showing "open" when it is closed.
