Ford Freestyle Fog Light
Diagnosing the Most Common Ford Freestyle Fog Light Issues
Aside from your headlights, you also need the aid of your Ford Freestyle fog light when you're driving at night or during worst weather conditions. The fog light is an essential component that provides you safety. But if you think that they are starting to show some defects, don't risk. Troubleshoot the problem first to determine the right way to fix it.
Dimming is caused by two things: first, hazy or cloudy fog light lenses. Try to look at the plastic or glass fog light covers on your car. If there is a visible white film on the surface of the lens, then it is confirmed-oxidation is the reason why the light beams are faint. Second reason is bulbs that are slowly dying out. When the light beams are starting to look pale, it indicates that the bulbs will soon get busted. What you should do is to observe the filaments of the bulbs while they are on. If they look burnt and black, expect your bulbs to die really soon. Replace them immediately to keep your fog lights working.
When your fog lights don't light up, you should check the fuse immediately. A blown fuse affects not just one but all of the light bulbs in the fog light assembly. To assess the fuse, you need to open the fuse box, which is located under the dashboard. Use a voltmeter to check if there's power flowing through the fuse. Place the black end of the wire on any metal part in the vehicle such as a bolt. Put the red wire on the fog light fuse. If you get any voltage reading, it means that the fuse is not busted. You should move on to next diagnostic test to find the real cause of the problem.
You've already checked the bulbs and the fuse, and you have confirmed that they are both working fine. However, the fog lights still don't work. This time, you must check the wires and the wiring harness. Corroded wires impede the flow of electricity. This could be the reason why the bulbs don't work. Inspect the wires visually to see the signs of rust. Also, examine the wire connections. Make sure that the cables are tightly attached to the harness.
