the only thing i can find with "search" is m17 and m18. both do not say anything about fog lights. which fuse is for the fog lights?

thanks, doug

 

There is not a dedicated fuse for the fog lights. Why do you ask? Tell us your story.

 

i have a pair of aftermarket fog lights and they stopped working last night. it's a pain in the butt to check or change the bulbs, so i wanted to check the fuse first. the fuse that came with the fog light kit is ok.

 

I suspect this is the same problem most people have, your fog lights are likely to high of a wattage to operate directly off of the factory wiring. The computer reads a problem and shuts them down. I think the stock fogs are 42 or 45 watts. anything higher "might" work briefly before the computer reads an error.

they should be wired so that the power for them comes from the battery via a seperate relay to avoid that problem.

 

i did that (power for them comes from the battery via a seperate relay).

 

How long have they been opperating.

 

two months?

 

Did you have to ground them? If so, check your grounds.

 

Are you using the stock wiring to trigger the relay? If not, then seeing as you ran seperate power feed via a relay from the battery then the only fusing would be in the new wiring you installed. So the jeeps wiring isnt part of the problem.

As mentioned above, recheck your grounds, they are a source of many headaches.

I have popped a fuse inexplicably on my KC's twice, I cannot track down the problem but i put in a new fuse and everything operates and tests correctly (I am guessing intermittant short but i cant locate it) My lights are NOT grounded at the bumper as some people do, I had issues with that so i am grounded at my relay under the hood.

 

i will check the ground.
