What is the reason why the rear light of Corolla is always on and cannot be turned off?

First, check whether the switch has been triggered, and then consider the issue of the car light circuit failure. Here is some additional information: 1. Three modes of car lights: ON is the always-on mode. When this switch is turned on, the ceiling light will stay on and will not turn off even after the car is locked. DOOR mode means the light will only turn on when the door is opened. OFF is the off mode. Selecting this mode will keep the ceiling light off and it will not light up. 2. Other reasons: If the always-on mode is accidentally activated, the rear seat light will stay on after the vehicle is turned off. If the rear seat light remains on even after the switch is turned off, it could also be due to the vehicle door not being closed properly when getting out of the car, which can cause the interior light to stay on.
I used to drive a Corolla, and the rear interior light wouldn't turn off, which was quite a headache. The main reasons are often that the door isn't closed properly or the door lock sensor is faulty. The Corolla is designed so that the light turns off automatically when the door is closed, but if the sensor gets dusty or stuck, it may mistakenly think the door is still open, causing the light to stay on. Alternatively, it could be due to a damaged light switch or a short circuit in the wiring. I once encountered this issue and found that the rear door lock needed a slight adjustment—just a gentle push or cleaning could fix it. If it's a switch problem, the part needs to be replaced. Don't underestimate this issue—leaving the light on for too long can drain the battery, especially in older cars where charging is slower, potentially preventing the car from starting. It can also affect nighttime driving safety. I recommend first checking if all doors are properly closed, then using a cloth to clean the sensor area. If that doesn't work, head to a repair shop promptly to avoid bigger problems.
