Ford Explorer Fog Lights
Diagnosing Your Broken Ford Explorer Fog Lights
Your fog lights are supposed to be mounted below the headlights of your Ford Explorer. It should give off a bar-shaped beam of light so that you can see the road better during poor visibility conditions. This light has a sharp cutoff at the top so you don't blind yourself or the drivers in front of you. However, you might find it difficult to get all of these benefits if your Ford Explorer fog lights don't light up. So, you'll need to check the different components that can cause this to find the ones that are in need of a replacement or a repair.
A broken fuse
Just like many of the other electrical equipment on your Ford Explorer, a broken fuse can be the reason why your fog lights have stopped working. So, you can start your investigation by locating your fuse box and using a plastic fuse puller to remove the fog light fuse. Afterwards, you'll need to inspect it for any signs of damaged wiring. If you find any, replace the fog light fuse with a new one and make sure that it fits perfectly inside the box. Then, turn on your fog lights and see if this solves the problem.
A broken fog light switch and relay
If the fuse is fine or if you've already replaced it and the fog lights still don't work, you'll need to turn your attention to the fog light switch and next. You can test if this is the faulty component by using a test light. Just connect the test light's jumper wire with the positive battery cable and then locate the fog light switch to check for connectivity at its various pins. If the test light doesn't turn on, then you have a problem with the switch. If it does turn on, you'll need to check the fog light relay. Make sure that you pay attention to any clicking sounds while doing the test. If you hear the clicks, then your relay is fine. If you don't hear the clicks, then your relay has failed and it will need replacing.
A broken bulb or wiring
If you've already ruled out the fuse, switches, and relays, as the broken components of your Ford Explorer fog lights; then you'll need to check out their bulbs and wiring for any problems. To do so, you'll need to use the test light on them. Start by taking out the old bulb and then stripping a bit of the insulation off the wiring harness. Then press the light against this area to see if it lights up. If it doesn't, then you'll need to have the wiring replaced by the experts in a service center. If the test light does light up, then the problem was with the old bulb. Install a new one in its place and you can be on your merry way.
