Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. So sorry to hear you're having trouble with your vehicle.
When the map lights in your Mariner stay on after the car is shut off, it can be due to a switch issue. First, check the switch for the map lights and make sure it’s not in the "on" position. Some vehicles have a dedicated switch on the overhead console that controls these lights independently of the doors.
If the switch is in the correct position, there could be an issue with the switch itself or one of your door "courtesy switches". Sometimes, a faulty door courtesy switch can cause the vehicle to think a door is still open, keeping the lights on.
If the problem persists, it might be best to have a professional diagnose the issue to prevent battery drain.
If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
