7 Easy Fix For Jeep Interior Lights Won’t Turn On When Doors Open Issues 

By now, we are familiar with the most common causes of jeep interior lights problems. So, now we will discuss the seven most common problems in detail along with their possible solutions and fixing costs. 

1. Faulty Dome Light: Flip the Switch in the Right Position or Replace the Bad Dome Light Bulb

The dome light is usually located in the middle of the ceiling of your jeep. It is the largest source of light in a car. If the dome light stops turning on when doors open, there may be a malfunction with the switch or there may be a blown fuse in the line.

First of all, go to check the switch if it is in the right position. Basically, the dome lights have three settings: “Off”, “ON”, or “Door”. When the “Door” option is activated the dome light will come on when the doors open. But if somehow the switch is in the wrong position, it won’t work.

So position the switch to the “Door” option and check again if it works when the door is opened. If it still doesn’t work, it may be a result of a bad dome light bulb. So, check the bulb and replace it as it’s required. To do so, pop the old light bulb out using a flat screwdriver and insert the replacement. 

In that case, the overall cost for a bad dome light replacement will run between $60 and $75. The expected labor cost can be between $30-$60 while the bulbs are priced between $10 to $25. 

2. Damaged Door Switches: Diagnose the Bad Door Switch and Replace It

Door switches or connectors are those which give the command to the interior lights to come on or off. These switches are located in the door jambs of your jeep. So, When you open the door, they will literally turn on and they will turn off when you close the door. 

But when the interior lights of your jeep don’t come on, the problem may lie in the door switches. To solve the problem, check the connectors if there is any power. In that case, you can use a multimeter. If there is no power, it means the switch is damaged. 

By then, go for replacing the bad door connectors. The average cost for bad door connectors replacement is between $85 to $105. The labor cost is estimated between $40 to $60, while the new connectors will cost between 10 dollars and 25 dollars.

Jeep interior light problems may be detected, when there is usually one or more blown fuses in the line. To explore the exact problem, take a multimeter and check if there is continuity between the terminals of a fuse. If not, it means it is blown.

4. Damaged wiring harness: Fix The Damaged Wiring

Once you replace the blown fuses but still have problems or the fuses are frequently getting blown, it means there is a wiring problem in the line. In most cases, it may be the result of a short circuit. 

So, visually inspect all the locations where the wires are usually bent and crimp. If the wires are loose, broken, or blown, remove them and replace them with a new piece of wire. 

On average, the cost of fixing a damaged wiring harness is between $1000-$1300. The labor cost is roughly between $400 to $500, while the wire harness will cost from $300 to $700.

In that case, a new light switch can cost you between $10-20 while the mechanic will charge from $40 to $60.

A faulty dashboard cluster can also be the reason for your jeep interior lights problem. The dashboard cluster also called the instrument cluster is the part of your jeep where all the meters are installed. So, if there is any issue detected in the instrument cluster, it can badly affect the lights from working.
