Ford Mustang Fog Light Bulb Troubleshooting
Fog lights are designed to provide you with extra road visibility-and in turn, road safety-when driving through dark or precipitous terrain. When driving through thick fog, snowfall, or rainfall, working fog lights can give you a clearer view of the road as compared to your standard headlights. That being said, you'll want to keep your Ford Mustang fog light bulb working at all times. And when your bulb begins to act up, you're going to want to diagnose the problem and solve it right away. So to help you out, here are some handy troubleshooting tips to live by.
Often times, a dimming fog light could indicate that your bulb is dying. Often times, having just one faulty fog light, rather than two, would be a telltale sign that your bulb is at fault and not any other component. In order to find out if your bulb is broken, remove it from the fog light and inspect it. This may require you to remove the entire fog light component, depending on its design. Otherwise, removing the light cover will easily give you access to the bulb. If the light bulb filament is blown, then that serves as confirmation that the bulb is dead and that you need a new one.
If the bulb isn't the problem, then you're going to want to check the fuse box. Remove the fuse box panel/ cover then follow the instructions on the inside of the panel to find the fuse for your fog light. Remove this fuse and examine its condition. If it's popped, then you'll need to have it replaced. However, if it's still in good condition, then return it to its proper position and test the fog lights if they work then.
When both your bulbs and fuses seem to be in order, check your wiring for damage. Trace the wiring of the fog light and inspect it for cuts or damage; a worn out wire could be the culprit behind your failing fog lights. When you find wire breakage, have these wires replaced immediately.
