i checked my battery, the started was hot wired and turn on but wouldnt afterward when key was inserted. im not sure if the relays are bad or the fuses.

I have been losing coolant and running hot pressure tested system and found no leaks any ideas on this

My fuse for the headlights burned and melted into the fuse location. I was told this is a common problem for the Aviator. I want to know if you have to replace the whole box, or can the fuse location just be cleaned and a new fuse entered. And is the dealer the only one that can replace the box?
