2000 Ford F-250 performed recall but problems still exist wi

Well, got a ticket for no brake lights on my way to work this morning. Once the sun was up, I went outside and looked under my dash to find a fuse, #13 which is a 20amp fuse burnt out. It shows as being for brake lamps, speed control module etc.. I pulled a replacement fuse and proceeded to replace the burn fuse. Suddenly I smell something burning. I look out from under the dash to see white plumes of smoke billowing from around the edges of my hood. I immediately pulled the fuse back off, smoke still billowing. Fearing the worst, I pop the hood release, run to the front of my truck and carefully unlatch my hood and let it pop up. Tons of smoke disperse, and I can see smoke coming from the speed control switch. There is what appears an electrical harness and switch connected to the booster, and the smoke was coming from that switch. I checked if my truck starts and it did.

Drove the truck in my parking lot to make sure I still had brakes etc...good except no brake lights...arggg..ok..so I got off work early and drove it to my dealer. They looked at it and said yea, that my truck had that recall and it still had not been done. It did not appear to have any other damage other than the cooked switch.

They replaced the switch, but alas..I still have zero brake lights, no cruise control, no horn and my underhood light is also zero go. All fuses, both under the dash and under the hood are now good. They won't repair whatever else is wrong now, claiming they are only responsible for the recalled item and not any damage caused by it's malfunction....makes me want to shoot someone....

So, anyone have any ideas what else can be wrong now? Everything was working before the toasted switch.

I checked the basics such as the fuses, the bulbs etc. I closely inspected the area after I got the truck home from Ford and there is zero damage visible anywhere around the burnt switch. There is one cluster of wires in a harness under where the switch was burning, and I checked it and the wires are perfect, with no sign of any heat damage. Ideas from anyone with more exp. in this than me?
