What are Interior Lights?
The dome lights, known as interior lights, play an important role in illuminating the cabin of a truck, car, bus, or any other vehicle. They are seen overhead and have auto-lighting switches.
The automatic dome lights turn on and off automatically when the door opens and when the engine is turned off. Many automated dome lights are designed to fade to assist the eyes. Dome lights also give better lighting for drafting a report or reading a map.
A dome or interior light emits colored lights such as red, blue, or green instead of white light. Their replacements exist in various materials and designs and require complete assembly.

Why Won’t the Jeep Interior Lights Turn Off?
The interior lights of the jeeps are designed manually and functionally to operate automatically whenever you open and close the vehicle’s doors. Sometimes, there is malfunctioning where the light stays on always and doesn’t get turned off.
I have created the infographic below that shows why Jeep interior lights won’t turn OFF. (You are welcome to use and share, but please credit back if you do so.)
The following issues cause this kind of experience:
1. The Issue with Rear Dome Light:
The rear dome light is turned on accidentally, so it is better to keep an eye on it. It can be turned on and off by simple press. This light can be accidentally tapped during loading and unloading the things from the back.
Children also love to play with lights by pressing the switch, which can sometimes lead to frustrating situations.
It is also recommended to check the connectors indoors, which can sometimes create an issue with turning interior lights if they are not connected to the door connectors. This dome light will automatically turn off after 15 minutes, even if it is left ON.
2. The Issue with Dimmer Switch:
The issue with the functioning of the interior light can be manipulated through the dimmer light switch. Sometimes, there is an issue with the settings/position of the knob.
If the knob is set to 'Complete ON' or in 'Dome Light ON' position (The setting, which is adjusted to the furthest position), there is chance that the interior lights are turned ON.
3. Failure in Closing the Doors:
The vehicle’s interior lights are connected to the vehicle’s door. Lights are also connected to the trunk in some cases.
When the door is opened, the lights turn on and turn off after closing the doors. If in some cases, the interior lights still do not turn off, the issue might be with the failure to close the doors properly.
4. Issue with Door Connectors:
If the light switch is not the case, check the door connectors.
The interior lights sometimes pose an issue in functioanlity when you take your jeep’s door off and then forget to reconnect the cables.
The door connectors must be connected for interior lights to work properly. It is better to look at the connectors to see whether they are fastened in good shape.
5. Faulty Instrument Cluster:
The issue with the instrument cluster’s ground fault can sometimes cause the dome lights to stop working. It is an electrical failure in the system.
This issue can be fixed by connecting the new instrument cluster.
This issue can be fixed after detection. Although the issue is less in new models, there are considerable number of reported cases from the old ones.
6. Damaged Switch:
There are lights fitted in a fashion with a manual switch on the vehicle’s roof, door, and dashboard. Sometimes, the interior lights won’t turn off if the switches are damaged, leaving the interior light in ‘ON’ position.
7. Faulty Fuse:
The stock dome light can be burnt due to a faulty fuse in your Jeep. Therefore, you have to be very careful while changing the fuse.
Many jeepers complain that as soon as they connect a new fuse, that also gets burnt immediately.
The issue could be a rubbed wire on the passenger side floorboard, specifically near the harness, where it turns and proceeds up the column to the light.
DTC Relevant to Interior Lights Stays On:
Diagnostic Trouble Code (DTC) | Codnition to log DTC |
B2615 |
|
B3801 | When the Body Control Module (BCM) detects that the signal circuit for the dome lamp switch is grounded when the switch is activated, it will immediately turn on the dome lamps. |
