We have a 02 F250 and it has electrical issues. Supposedly the horn relay is built in the fuse panel. It shorted out sometime last year and the electrical has been all messed up since. The horns blows at random, windows go up and down whenever, cruise works occasionally, back doors won't open at all, ect. My question is if we change the fuse box, which was recommended, do we need to change GEM box? Also will this need to be reflashed. Any input on this would be helpful.
