What Causes Inside Car Lights Won’t Turn Off

The interior lights of your car have been designed to function both manually by the different hand switches on the roof next to the light, on the doors and the dashboard, and automatically whenever you open and close the doors of your vehicle.

However, sometimes there may be a bit of malfunctioning whereby the lights stay ON instead of going OFF based on their original way of functioning. If you experience this situation, it is likely caused by any of the following.

Failure to close door properly

Your car’s interior lights are linked in connection to the door of your vehicle, and in some cases, to the trunk. The lights turn ON when you open the doors or the trunk, and they turn OFF when you close them.

Therefore, if you find out that your car’s interior lights fail to turn OFF at any point in time, the challenge is likely traceable to one or more doors you failed to close properly.

Damaged or faulty switch

The lights are fashioned with a manual switch at the roof close to the light, on the door, and on the dashboard. If you discover that the interior lights won’t go off, it may be due to a switch you manually turned ON and forgot to turn OFF.

If this is not the case, then it is likely that one or more of the switches have been damaged, especially leaving the functionality at the ON position.

Adjustment of the dimmer switch to its highest position

Your car lights dimming function is performed by a setting located at the left side of the wheel on the dashboard. When the setting is adjusted to the furthest position, it usually affects the interior lights of your car.

Therefore, if you find out that your car’s inside lights are ON and won’t go OFF after checking for the other control points, change the dimmer switch setting.

How to Fix Inside Car Lights Won’t Turn Off

Having understood that your vehicle’s dome lights are usually located on the roof, door, and under the dashboard, and the reasons why your car’s interior lights won’t turn off, it is also crucial to know how to fix the problem.

The following are methods of fixing the problem if your car’s interior lights won’t turn off.

Adjust the light’s switch

Firstly, it is easy to turn ON the lights using the switch close to the light on the roof of your car or the dashboard and forget to turn it OFF. 

Therefore, the first solution is to check whether you mistakenly forgot to switch OFF after switching it ON manually. If this is the situation, turn it OFF.

Properly check the light switches at the doors

Another point on control of your vehicle’s interior lights is the doors, and in some cases, the trunk inclusive. Therefore, you should carry out a proper check on the switches on the doors. 

You may have to open and close each of the doors one after another to see if the light will turn off. If this doesn’t work, locate the manual switch on each door and press it to turn off the light. 

You would feel a click once you press the switch. If you don’t feel the click or after this action, the light doesn’t go off, the switch on the door is likely faulty. Try to fix the defective switch yourself or see a technician.

Properly check the headlight switch setting

Some cars have a knob responsible for controlling the brightness of the lights on the dashboard. If the setting of this light is on the highest, it may likely affect the interior light and cause it not to go off. Therefore, if you find out that the setting is on its highest level, change it to fix this challenge.

Check the wiring or see a technician

Suppose the suggestions above do not work after applying them. In that case, you may want to trace the wiring of the interior lights of your car to ascertain any disconnection or faults that cannot be easily discovered by merely carrying out the above operations.

The wiring of the interior lights of your car runs from the switch at the door across the frame into the dashboard of the vehicle. Therefore, you would need to be careful in performing this action; otherwise, it would be best to consult a professional auto technician to solve this problem.

Optional 2: Locate each door switch by opening and closing one after the other.
