Ok some body help me please. I have a 99 lightning and i have had some trouble with the fog lights, but mostly some simple stuff like lightbulb blowouts and stuff like that. But yesterday one light went out and not the other. So i tried to change the one bulb and i did ( both bulbs are on now) but when i bolted the fog light back up and tured on the fog lights both bulbs were now out. I checked the fuses and the blue 15 was blown so i change it and it still didnt work. i check the fuse again and my brand new fuse just blew . I did this one more time with another new blue 15 fuse and it did the same thing. So i gave up and this is why now i am writing to you guys to see if anyone else has this problem and what did you do. Thanks

 

I feel your pain. Im going through the same prob right now myself. I think the fuse inside the cab for the fogs is a brown 5 amo fuse? Altleast in my 00L?

 

Guys, check your bulb installations. You obviously grounded something.
