2001 f250 dash & tail lights not working

my buddy has a 2001 f250 diesel 4x4 truck & the tail lights & dash lights stopped working on him the other day. he checked the fuse & it was blew, so he changed fuses & as soon as he turned on the running lights the fuse blew again.

i am just plain stupid when it comes to an electrical problem, & i know some of you are friggen geniuses on electrical problems. i don't know if that stuff runs off of a relay, or just the fuse. where would we start on this turd (the problem, not the truck )? by the way, me trying to read an electrical diagram would be about the same as me splitting an atom.

2001 f250 dash & tail lights not working

Most of the time I leave the new stuff to guys that work on them, I went to school for electrician for aircraft, but I'm to old to work on all this new stuff. but maybe I can help a little. First what fuse is blowing, now days the light switches have self setting breakers right in the light switch. so what fuse gets blown. then you have all your lights coming off that switch so if something has a short it will blow the light switch breaker so you don't take out all your lights. so find out which fuse you are replacing, post me in the morning or when ever.

Later 35terraplane

it's a small plastic two bladed 15a fuse under the hood in the distribution box. his brake lights, turn signals, & hazard lights all still work. he changed the light switch & nothing changed.

This is why I don't work on factory wiring, they use all these boxes and you almost need a diagram for every car and truck. So A 15a flat fuse is blowing in a distribution box, how many wires go into it and can you tell where they go. You have replaced the light switch, but that still doesn't mean the wires that plug into the switch are not touching. The brake light, turn signals, and hazard light are all the same filament, tail light is the other filament in bulb.
Back to the box, it more than likely is a hot feeding a couple circuit, I'm not sure what colors ford uses and if they are the same on every car and truck. look and see if any of the colors coming out of the box are the same as back at the tail light. Ford Use to use a striped wire, see if there is a wire at both end the same color and stripe.
If anyone reading this, that knows wiring on a Ford And has a diagram, please jump in. Somewhere the tail light and the dash light, are crossing paths causing a fuse to blow, in a distribution box, by the way where is this box under the dash, under the hood, or where. I see no need for the dash wires to run outside under the hood, but I'm not going to assume they don't.

If know one jumps in I will be here but I'm just doing this in my head, and don't have a clue what the diagram looks like. So I might sound like I'm drunk sometimes, and maybe I should be but we will try.

It might sound like I don't know what I'm doing, But I have a plan LOL

the box that the fuse is blowing in is under the hood of the truck. it has about 10-12 small fuses, about 10-12 of the very big fuses, and 5-6 relays. there is a bunch of wires going into the bottom of this thing.

Sounds like the only 15amp fuse in the battery junction box is light switch control and then there is one for daytime running lamps. Anyways, there is power out of light switch connector to interior lights and then to exterior lights, a parallel circuit seperated at switch, but the fuse would not know the difference. Looks like there is a feed going to trailer lighting also thru exterior lights circuit. You might pull apart the trailer connector to see if the short to ground is there. Or you could ohm out at light switch connector to see if its the dash lighting short, or external short, then go from there. GL Hope to not confuse you more.

I would look at the connector for the trailer hookup. Probably a short in there(if it has one).A short in the tailight circuit will knock out the power for the panel illumination as the fuse for the tails has a feeder for the instrument panel fuse. If the instrument panel was the problem it would pop the smaller instrument panel fuse (probably 5 amp) and the tails would not be affected.

we unplugged three harness connectors under the back of the truck (behind the bumper) yesterday. one was the tail lights, one to the trailer connector, & i think the other was for the license plate lights. even will all three unplugged it would still pop the fuse just as soon as the switch for the running lights was turned on.
