Ford Expedition Fog Lights

Common Issues of Ford Expedition Fog Lights and the Reasons behind Them

Road visibility is tough when you are driving through thick fog. Even your sturdy Ford Expedition will find it hard to drive in that condition without the help of a reliable set of fog lights. Fog lights are one type of auxiliary lighting that allows drivers to see and be seen clearly even with the presence of fog. These lighting gears are strategically angled downward, so the light beam can reduce glare and illuminate the road. In reality, your Ford Expedition fog lights are rarely being used, but this does not mean that they are free from harm and other technical dilemmas. Here are some of the usual problems encountered by most Ford Expedition owners with their fog lights and the usual reasons behind these issues:

Moisture inside the fog light housing

Since your Ford Expedition fog lights are your vehicle's frontline soldiers against fog, moisture tends to accumulate inside the fog lights' housing. This happens when water droplets from the air seep through fog light covers as your vehicle passes through a cloud of thick fog. This should not actually happen since your fog light covers are supposed to be water-tight, but there are some cases when one or both fog light housings loosen over time. To solve this issue, you can buy a new set of fog light housing. But if the budget is tight, you may just opt to secure the edges of your fog light covers with a reliable sealant.

Busted fog light bulbs

Although your fog lights are seldom used, the fog light bulbs are still prone to premature wear and failure. Several Ford Expedition owners complain about their vehicles' fog lights not turning on. There are many possible reasons for this, and one of them is moisture inside the housing. When water gets inside the housing while the fog lights are on, there is a huge chance that the bulbs will explode. Aside from a busted light bulb, you will also end up with a shattered fog light cover. It is also possible that the bulbs are just loosely attached to the sockets. Sometimes, the bumps you hit while driving can cause the light assemblies' bulbs to get detached from their sockets. You can try tightening the bulbs in place. But if nothing happens, you may want to check for a blown-up fuse.

Other troubleshooting tips

In some cases, the Ford Expedition fog lights are working, but they tend to dim or flicker now and again. If this happens to you, you may want to check the electrical connections and wiring harness of your fog lights. This may be caused by interruptions in the flow of power from the source to your fog lamps. Other reasons include weak light bulbs, short circuit in the wirings, a defective ballast, or a faulty fog light switch.

  • Practical Ways to Care for Your Ford Expedition Fog Lights

    Although your Ford Expedition fog lights are not as frequently used as your headlight assembly, these fog lamps are absolutely as important. They allow you to survive the travails of driving through a thick cloud fog by effectively illuminating the road without the hassles of excessive glare. Just because you are not always using your fog lights, it doesn't mean that it is okay not to take care of them. Just like all the other valuable parts of your Ford Expedition, these auxiliary lights are susceptible to wear and tear, especially if they are not properly maintained. If you do not want to end up with a busted set of fog lights, follow these practical but very useful maintenance tips:

    Maintain a water-tight fog light housing.

    It is important to keep the interior of your fog light assembly moisture- and dirt-free. Any form of contamination inside the fog light cover can be very detrimental to your bulbs and electrical connections. If you are experiencing this problem, you need to remove the fog light covers to get rid of the water inside. When you put the cover back in place, it is recommended to seal the area around the fog light housing using commercial headlight sealants or auto paste wax. This will keep the water out of the fog light assembly, and it will also protect the inside from oxidation.

    Check the wires and the bulbs regularly.

    Your fog lights are only as good as the light bulbs and the other components of your fog light assembly. When one of the fog light assembly components fails, you may now bid your fog lights goodbye. To avoid this hassle, you should perform habitual check-ups on your bulbs, ballast, sockets, wirings, switches, and fuses just to make sure that they are all in excellent condition. This will also prevent you from losing your fog lights just when you need them the most. Checking these components from time to time will allow you to change them as soon as you see initial signs of wear.

    Always clean the fog light covers thoroughly.

    Just like your headlight lenses, fog light covers are also vulnerable to heat, humidity, and oxidation, which are the top causes of yellowish or dingy fog lights. Cleaning both the exterior and interior portions of the fog light covers will somehow prevent your fog lights from becoming cloudy. After all, who'd want a pair foggy fog lights?
