Culprits behind Having No Light Output on Mazda Tribute Fog Lights
Fog lights are quite important when it comes to driving through low-visibility weather. When something goes wrong with your Mazda Tribute fog lights, it is very important for you to be able to identify the real problem so you can provide the real solution. The most common problem encountered with fog lights is having no light output, which can have a wide range of causes. Here are some troubleshooting tips to help you pinpoint the exact problem:
Burned out fog light bulb
Since the fog lights are quite easy to remove, check the bulb of the fog light that is not working. But remember to unplug the electrical plug from the fog light assembly before getting to work. When ready, turn the fog light counterclockwise to remove the bulb from the housing. If you see any black or dark burn marks, it's time to replace the bulbs.
Broken or blown fuse
When the fog lights don't light up, it may be caused by a blown or broken fuse. To know for sure, open the fuse panel and check the fuse for the fog lights. Make sure the metal strip inside it is not blown or broken. Otherwise, you will have to replace it with a new one.
Damaged or frayed wires
Another cause of no light output is damaged or frayed wiring. To check, open the hood and trace the wiring from the fog lights to the firewall. Observe the wires for any damages to the wiring. If you see any frayed wires, make sure you contact a professional mechanic to take care of that to avoid burning up your Mazda Tribute from under the hood. If you don't see any damages, though, you may use a voltmeter to check if there is any electricity flowing to and from the fuse. If you are able to get a reading, electricity is flowing, and the fault does not lie in these wires.
Test your fog light switch inside the cabin by using a voltmeter. And same as with the wires, if you get a reading, it means electricity is getting through the switch. Otherwise, you may need to replace the faulty switch.
