Why Ford Expedition Interior Lights Won’T Turn On

Blown Fuse

The most common cause of interior lights not working in a Ford Expedition is a blown fuse. To check the fuses, open the fuse box located under the hood. Look for a fuse labeled interior lights or dome lights. If the fuse is blown, replace it with a fuse of the same amperage.

Wiring Problems

Another possible cause of interior lights not working is a wiring problem. The wiring for the interior lights can be damaged by corrosion, heat, or physical damage. To check for wiring problems, inspect the wiring harness for damage. If you find any damage, repair or replace the wiring harness.

Bad Switch

The interior light switch can also fail, causing the interior lights to not work. To check the switch, turn on the ignition and press the interior light switch. If the interior lights do not come on, the switch is bad and needs to be replaced.

Bad Bulbs

Finally, the interior lights may not be working because the bulbs are bad. To check the bulbs, remove the interior light housing and inspect the bulbs. If the bulbs are burned out, replace them with new bulbs.

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

Your Ford Expedition’s interior lights are an important safety feature, allowing you to see clearly inside the vehicle at night or in low-light conditions. If your interior lights won’t turn on, it can be a major inconvenience. It can also be dangerous, as you may not be able to see clearly enough to drive safely.

There are a few possible causes for this problem, and it’s important to troubleshoot them in order to find the solution. In this article, we’ll walk you through the steps of troubleshooting a Ford Expedition interior lights problem.

Step 1: Check the fuses

The first step is to check the fuses for the interior lights. The fuses are located in the fuse box under the hood of your Expedition.

To check the fuses, you’ll need a fuse puller. You can find one at most auto parts stores.

Once you have the fuse puller, open the fuse box and locate the fuses for the interior lights. There are usually two fuses, one for the front lights and one for the rear lights.

The fuses are labeled, so you can easily identify which ones are for the interior lights.

To check a fuse, simply remove it from the fuse box using the fuse puller. If the fuse is blown, it will be blackened or melted. If the fuse is not blown, it will be clear or copper-colored.

If a fuse is blown, you’ll need to replace it with a new one. You can find replacement fuses at most auto parts stores.

Once you’ve replaced the fuse, test the interior lights to see if the problem is fixed.

Step 2: Check the wiring

If the fuses are good, the next step is to check the wiring for the interior lights. The wiring is located in the headliner, the pillars, and the floor of the vehicle.

To check the wiring, you’ll need a voltmeter. You can find one at most auto parts stores.

Once you have the voltmeter, turn on the ignition of your Expedition. Then, use the voltmeter to test the voltage at the connectors for the interior lights.

The voltage should be between 12 and 14 volts. If the voltage is not present, there is a problem with the wiring.

You’ll need to trace the wiring from the fuse box to the interior lights to find the problem.

Once you’ve found the problem, you can repair the wiring or replace it.

Step 3: Check the light switch

If the fuses and wiring are good, the next step is to check the light switch. The light switch is located on the dashboard of your Expedition.

To check the light switch, simply turn it on and off. If the interior lights do not turn on or off when you operate the light switch, the switch is faulty.

You’ll need to replace the light switch. You can find replacement light switches at most auto parts stores.

Once you’ve replaced the light switch, test the interior lights to see if the problem is fixed.

Step 4: Check the dimmer switch

If the fuses, wiring, and light switch are good, the next step is to check the dimmer switch. The dimmer switch is located on the dashboard of your Expedition.

To check the dimmer switch, simply turn it up and down. If the interior lights do not dim or brighten when you operate the dimmer switch, the switch is faulty.

You’ll need to replace the dimmer switch. You can find replacement dimmer switches at most auto parts stores.

Once you’ve replaced the dimmer switch, test the interior lights to see if the problem is fixed.

Conclusion

If you’ve followed these steps and the problem is still not fixed, you’ll need to take your Expedition to a qualified mechanic. The mechanic will be able to diagnose the problem and repair it.
