Hello, I'm new to the forum and new to repairing vehicles in general. I really like my '10 Explorer and want to keep it in good working order as long as possible. My first of many questions: The lights on the immediate left and right of the interior Dome light do not function when the vehicle engine is running. However, when I turn off the engine and open the door, the 'side' lights function as intended. I have checked the fuse (23) and it is the correct amperage and it is in good working order (obviously). Does anyone have any insight into what could be going on with those side lights? Thanks very much for any assistance or other insights.
