Sooo, it's pretty annoying when everytime I turn my car off, my fog light fuse burns out. I noticed one day that my fog where not coming on, so I checked the fuse, and sure enough, it was burnt. So I replaced it, turned on the headlights with the fogs and they worked. They worked in fact until I turn my car off. Then, when I look at the headlights when I get out of my car, before they turn off automatically, the fogs aren't on, but the switch is. Check the fuse again, and it's burnt. Replace the fuse again, works fine. Stop to get gas, turn of the car, pumping gas, check the lights before they went off, fogs aren't on and the fuse is burnt again. I have no idea why it's doing this. They were working fine until the fuse burnt, so I guess something made it blow and now they keep blowing. Any help?

 

To blow a fuse means a short. Chect the wire harnesses going to the lights carefully for spots that could be rubbing on metal somewhere. Since it seems that the fuse does not blow immediately, that the lights are on for a while, you could have a light bulb where the filament inside the bulb is warping with the heat and shorting internally. Take the bulbs out and examine them. If you can't find any other cause, take out one bulb and drive around and see if the fuse blows.

 

I had a time last year where I keep popping fog light fuses. After taking the fog lenses apart, I realized that the connectors inside one of the lenses was compromised and creating the short. Ever since, I've been wrapping the internal fog connectors with electrical tape before closing down the end-cap.

Haven't blown a fuse since then.

 

Unplug the foglight assemblies from the chassis wiring harness and measure the foglight harnesses for a short.....If the short(s) are in the foglight harness then open up the foglight assemblies and check your bulb and positive lead to ground relationship...There should be a protective sleeve on the buld positive lead and the bulb's body & flange are negative.....the positive foglight harness & bulb are connected via a butt splice connector within the cap and the negative wire is attached to the bulb holding chassis!!!! You should find you problem pretty easily it's for a light circuit......

 

Okay, I will do that. If the fuse does blow with one bulb out, should I try taking the other bulb out and doing the same thing?

 

Are you talking about taping the wire where the fog housing meets the wire itself?

 

I'm talking about wrapping the wire connector *inside* the fog lens, where my short was occurring.

 

Ohhh, okay, I see now what you mean, sorry. So you had a piece of you fog light wire exposed, shorting out on a piece of metal?

 

Yep. That's exactly what happened. Pop your lenses off and see if that's your problem.

(edit) "Pop" is a relative term. After you've done it a few times, you can do it with your eyes closed. But if you've never done it before... PITA first time out.

 

Okay, I will take them out and inspect the wiring completely. Thanks, guys. I will update y'all on what I find, or don't find.
