Diagnosing Common Nissan Maxima Fog Light Bulb Problems
One of the worst things that could happen to you is to have failing fog lights as you're driving through thick fog. This could leave you barely able to see anything on the road, and it could also leave you vulnerable to an accidental collision. If you begin to experience any problem with the fog light bulbs, be sure to check them out immediately and have them fixed as soon as possible. This ensures that they will operate without any issue every time you need them to. For more information regarding Nissan Maxima fog light bulb problems, read on.
Fog light bulbs that won't turn on
This problem is commonly caused by a blown-out light bulb, a blown fuse, or a malfunctioning relay. The first thing you'll need to check is the bulb. Open up the fog light assembly and take out the fog light bulb. Check whether or not the filament inside is burned out; black or gray deposits coating the inside of the bulb are an indication of a burned-out bulb. You could also stick the bulb in another bulb socket to see if it turns on normally. Replace the bulb once you determine that it is burned out.
If the bulb is okay, open the Maxima's fuse box and look for the appropriate fog light fuse. Check the fuse to see if the electrical connection within the fuse is severed or burned out; replace the fuse if so. For the relay, you could test it with an ohmmeter if you wish. If you get no readings, that means there is no electricity flowing through it and that it should be replaced immediately. An easier test would be to put a new relay in the fog light relay slot. If the fog light turns on as normal after, then that means the old relay was problematic.
Fog light bulbs that flicker or turn off but work normally after being knocked gently
This is usually caused by a problematic connection in the electrical system. Open up the fog light assembly and inspect the fog light bulb and its socket. Check if the bulb is screwed in tightly and isn't wobbling around. Tighten the bulb as needed. Check the connection of the wires and bulb socket as well and make sure that they are secure. Too much dirt in the fog light assembly could also mess with the electrical contacts, so be sure to clean the fog light assembly with some electrical parts cleaner. For rusty or corroded electrical components, have them replaced immediately.
