Usual Problems Encountered with a Faulty Ford Explorer Sport Trac Fog Lights
Having a good set of fog lights for your Ford Explorer Sport Trac is crucial when you need to drive in hazy weather conditions. Unlike other automotive lights, these fog lights are specially designed to give more visibility and reduce glare when you are driving down a foggy road. So if you suspect them to be defective, then better troubleshoot immediately. Here are a few common problems encountered with defective Ford Explorer Sport Trac fog lights.
Single bulb failure
When just a single fog light is not working, check the part for a burnt out bulb. Removing the fog light bulb should not be that complicated. In fact, it requires mostly the detaching of screws. Once the screws are loose and the bulb is removed, inspect for signs of broken filaments. If you find one, then you should definitely find a replacement. In other cases, you will find hints of corrosion in the socket or connecting wires. This also affects the lights' condition, so make sure you maintain them too.
Both fog lights fail to work
Unlike a single bulb failure, when both fog lights fail to light, the first thing you should check is if there is enough electricity flowing to and from the fuse. For troubleshooting, you will need to use a voltmeter. You can buy one at your local auto supply store if you don't have one at home. If you don't get a reading with the device, then you have a faulty fuse. In some instances, you might also need to use the voltmeter to check if the fog light switch is defective. Additionally, check for corroding wires. There are cases when rodents found their way inside a vehicle's wiring system and chewed off the wires.
Fluctuating fog lights
When you find fog lights to flicker, especially when you accelerate, then you might have a faulty alternator. You see, there is a possibility that the battery is not giving enough power. As a result, the fog lights often fluctuate and flicker, especially when you hit the gas pedal.
Foggy fog lights
Foggy or hazed fog lights indicate that there is moisture trapped inside the housing. You will need to clean and dry them to retain the part's original functionality.
