Light question
My F350 just started having a light problem. There was a 20 amp mini fuse under the hood that was burned out. After I replaced it all my exterior lights have a problem. When I turn the switch on the lights all go on. But when I turn the switch off nothing goes off. I have to pull the same fuse once and put it back in for the lights to off. My 250 looks the same in the fuse box and light switch and works fine. I pulled all the relays under the hood, and put them back but they had no affect on the lights. I still had to pull the fuse to get them to go off. Is there another relay somewhere for the lights that is sticking? Or ? Thanks for any help. I tried switching the light switch with my 250 but it still did the same thing.

There is a relay box that has a "park lamp relay" inside it. The 20 amp fuse feeds this relay. It is associated with the remote keyless entry, and is driven by the GEM module. It must be what blinks the lights when you hit the remote key fob. The only description I can find on this relay box is it's located in the center of the instrument panel. I would assume this must be high up behind the radio.

Thanks for the reply Dave. It took me a while but I found it. It is left and just a bit lower than the radio. You can pull the radio and get to it. There are 3 relays together. A big blue one and two smaller black ones. It was the small black one that is toward the front of the truck. They could have engineered the wiring a little better. Thanks again. I would have looked forever without some idea where it was. I tried to rep you but it would not let me.
