How to Troubleshoot: 2019 Ford Expedition Interior Lights Won’t Turn Off

The interior lights in your 2019 Ford Expedition are an important safety feature. They allow you to see clearly inside the vehicle at night or in low-light conditions. If your interior lights won’t turn off, it can be a major inconvenience. It can also be a safety hazard, as you may not be able to see clearly when driving at night.

There are a few possible causes for this problem. The most common cause is a faulty interior light switch. Another possibility is a problem with the wiring to the interior lights. In some cases, the problem may be a bad fuse.

To troubleshoot this problem, you will need to first identify the cause. You can do this by following the steps below.

Step 1: Check the interior light switch

The first thing you should do is check the interior light switch. To do this, locate the switch on the dashboard. It is usually a small button with a light bulb icon on it.

Press the switch to turn on the interior lights. If the lights come on, then the switch is working properly. If the lights do not come on, then the switch is faulty and will need to be replaced.

Step 2: Check the wiring to the interior lights

If the interior light switch is working properly, then the next thing you should check is the wiring to the interior lights. To do this, you will need to remove the interior trim panels. This will allow you to access the wiring behind the dashboard.

Once you have access to the wiring, carefully inspect it for any damage. Look for broken wires, loose connections, or corrosion. If you find any damage, you will need to repair or replace the wiring.

Step 3: Check the fuses

If the interior light switch and wiring are working properly, then the next thing you should check is the fuses. The fuses for the interior lights are located in the fuse box under the hood.

To check the fuses, you will need to remove the fuse box cover. Once you have access to the fuses, look for a fuse that is blown or has a broken wire. If you find a blown fuse, you will need to replace it with a new fuse of the same amperage.

Conclusion
