Where are the head light fuses on a -04 quad cab 5.7?
I upgraded to bi-xenon--> and it works great
The only thing is, I have to change the fuses to 20 amps, but I can't find them anywere... They don't seem to be in the fusebox... Any one???
Thanks for your help!

I've looked in the fusebox! None of the fuses describe headlights. What numbers & descriptions(in the lid) does the headlight fuses have?
Thanks again

There is no specific headlight/headlamp fuse.
It is fuse #41 (foglamp) fuse.
That fuse feeds the fog lamp relay in the front control module and powers the fogs and heads.
Word of caution;
That circuit was designed for 15amps, so the wires are a little thinner and may burn with the extra 5 amps.

I see the last post was in 2007, however I am re-asking the same question. Where is the fuse or relay for the headlights? I'm having weird light problems. For my headlights, only the passenger side low-beams work, then on high beams only the drivers side work and nothing on the passenger side. Also, when I put on the hazard lights, only the back passenger tail light blinks. I've checked every bulb with a meter. Any help? I'm thinking my fcm may need to be replaced. I've checked the notorious rear tail light circuit boards. They are fine.

IDK but I dont like the part where you say you need to change them to a 20a. If they are less than that (10a/15a) and you are blowing them and feel the need to go to a 20a then that is a bad idea. Real bad idea.
