fog lights not working

Truck is in signature.All of a sudden my oem fogs dont work.I took a volt meter to the connection where the bulb plugs in and no juice.Checked the fuse and its good.I get 12 volts or so at fuse for fogs..The foglight illuminator lights at the switch when I pull the switch.Is there a relay somewhere under the hood.All the relays in the fuse box checked out good and none of them in my truck guide were labeled for the fogs anyways.Im at wits end.Looked for 3 hours and cant find a thing.If all else fails how do I cut the wires at the fog lights and run wire to cab with toggle switch?I know I need a relay right?Im not familiar with hooking up relays...Any help would be appreciated...If I knew where the relay was I think I would find my problem...

I don't know whats going on, but the factory diagrams do not show your truck having foglamps. I looked through everything, and even looked up the headlight switch diagram. They show the foglamp part of the headlight switch, but say "no connection" for your truck. Now if I look up a 2000 f150, they have a whole separate section in the diagrams showing the foglamp circuits.

Possibly these foglamps were added and that's why you cannot find the relay and related components?

No these are oem , listed on sales sticker. They are are built into the headlight switch, you pull the headlight switch out and they go on...

I must be going crazy, I thought you had a 2000 f350. Anyway, they did have them in 2002.

The fuse is #43, 10 amp, in the underdash fuse box. The relay is located in the same fuse box under the dash.

The links above are hopefully your fuse box. I keep looking and looking for the foglamp relay, and can't find it, and they do not list it as a replacement part. This means only one thing. They have built it into the fuse box, and it's not replaceable. We ran into this with the trailer tow running lights relay. Several people have had that go bad, and we found out the Ford engineers had a "better idea" and built it into the fuse box, and you have to replace the whole fuse box to fix it. Some people instead had added their own relay, bypassing the bad one in the fuse box.

A tan/orange wire leaves the fuse box to feed the foglamps.

If fog light is not working it is needed to be replaced...light is very essential for any vehicle so its better go to the dealor and ask him to replace the lights
