What fuse would it be since they are aftermarket fog lights? And the fuse box under dash or under the hood?

Also if the fuse popped what do I do so they don't short out anymore?

 

Okay well it depends where the wires ran for the fuse. Because if it is an inline fuse on the harness it'll just be in the lil fuse holder, or if it is like mine, which I ran to the fuse box under the steering wheel, it's there obviously. So once you know where the fuse is located pull it and check it. How long did you have the fog light son that 3rd night, longer than the other 2? And to fix the problem you just have to put a bigger fuse in, but the whole heavy duty harness could be needed since the wire could be too small and is heating up.

 

Not even that long. I put the bulbs in yesterday around 2PM. Used them that night for maybe an hour in a half, and used them today drove about 15 minutes worked fine. Parked at sheetz used the restroom with the fogs and car running(girl was in the car) came out and they were off and don't work?

 

By the way, I am pretty sure the heavy duty wire harness they were talking about was the one for the headlights, not the foglights.
