How to Fix a Roof Light That Won't Turn Off?

First, check if all doors are properly closed. Open and then firmly close each door. Next, inspect the door sensors one by one to see if they are malfunctioning, and replace them if necessary. If the doors are confirmed to be tightly closed and the sensors cannot be checked, it is recommended to visit a 4S shop to inspect the circuit and perform repairs.
I've been driving for over a decade and have encountered the issue of interior lights not turning off several times. It's usually caused by a stuck door switch or faulty manual switch. For example, if a door isn't completely closed, the system mistakenly thinks someone is entering/exiting, keeping the lights on. You can first check if all doors are properly closed, then try manually toggling the light switch several times to reset it. If that doesn't work, it might be a wiring short circuit or faulty control module - check if any fuses are blown. A simple solution is disconnecting the battery negative terminal with a wrench for a few minutes then reconnecting. If the problem persists, visit a repair shop immediately. Otherwise, the battery will drain quickly, especially in cold weather when starting becomes difficult - you might even need a tow truck, which would be real trouble.
Oh dear, as a housewife, my husband's car had this issue before. The dome light staying on is really annoying. It's most likely a problem with the door sensor, like the door lock not popping back properly, making the light think the door is open. I suggest you try opening and closing each door a few times, listening for any unusual sounds. You can also check the interior light switch button—it might be stuck in the 'on' position. If you can't fix it yourself, don't force it. Ask a car-savvy friend to help remove the switch panel and do a simple check on the wiring. This drains the battery quickly, so try to turn off the light after parking to avoid a dead battery—otherwise, it'll be troublesome for school drop-offs and pickups. Take it to a professional repair shop as soon as possible, or a small issue could turn into a bigger, more expensive problem.
