If you’re having trouble turning on your fog lights, it can be frustrating and potentially dangerous if driving in foggy or inclement weather. There are various reasons why your fog lights may refuse to turn on, and it can be difficult to pinpoint the exact cause.
In this article, we will discuss the common causes of fog light issues, how to diagnose the problem, and potential solutions to get your fog lights back in working condition.
Possible Reasons Why Fog Lights Won’T Turn On
Possible reasons why fog lights won’t turn on include blown out fog light bulbs, faulty fog light switch, problems with the electrical system, and issues with the fog light relay. If your fog lights are not turning on, it could simply be due to a blown out bulb, which is an easy fix.
However, if the bulb is not the issue, it could be a more complex problem with the switch, the electrical system, or the relay. In order to determine the cause of the problem, it is best to consult a professional mechanic to diagnose and fix the issue promptly.
Ignoring the issue could put your safety at risk, as fog lights are an essential component when driving in adverse weather conditions.

Step 1: Checking The Fog Light Bulbs
To troubleshoot why your fog lights won’t turn on, the first thing you should do is check the fog light bulbs. You can find them beneath your vehicle’s headlights, either on the bumper or in the grill. Look for any signs of a blown out bulb, such as blackened or broken glass.
If you find one, the solution is simple: replace the bulb with a new one. To do this, remove the old bulb by gently twisting it counterclockwise, and replace it with a new one in the same way. Make sure the new bulb is functioning by turning on your vehicle’s headlights and testing the fog lights.
Step 2: Inspecting The Fog Light Switch
To inspect the fog light switch, start by locating it. Check for any visible damages, like cracks or signs of wear and tear. If there are no visible damages, test the switch using a multimeter. This will help ensure that the switch is working properly.
Don’t forget to refer to the car’s manual on how to use a multimeter and to always exercise caution when testing electrical components. By following these steps, you can troubleshoot why your fog lights won’t turn on and potentially fix the issue yourself.
Step 3: Checking The Electrical System Of The Vehicle
To check the electrical system of your vehicle, start by examining the electrical connections. Look out for any loose wiring that may be the cause of the fog lights failing to turn on. Use a clamp meter to test the electrical current and ensure that the voltage is sufficient.
If the voltage being supplied to the fog lights is low, it’s possible that there is a problem with the alternator or the battery. Check if there are any blown fuses and replace them if necessary. If none of these checks reveal the cause of the problem, take your vehicle to a certified mechanic who will be able to diagnose the issue and provide a solution.
Step 4: Testing The Fog Light Relay
In order to test the fog light relay, you must first locate it. The relay is typically found in the fuse box under the hood. Once you have located the relay, carefully remove it. Use a voltmeter to test the relay by touching the probes to the pins.
The voltmeter should read between 12-14 volts. If it does not, then the relay may be faulty and need to be replaced. Testing the relay is an important step in diagnosing the reason why your fog lights won’t turn on.
By following these steps, you can determine the cause of the problem and fix it accordingly.
