I am sorry your having this problem
will one of the terminals on the relay physically be brown or burnt or have black marks on it when this happens ?
the only thing that will cause that kind of heat is high resistance and high resitance is caused by a bad connection
remove the relay and the terminal in the box the relay plugs into take something like a small dentist pick or something like that and tweak over the terminal center in the box so it is just about closed off visually
do that to all 4 terminals so you know for a fact when a new relay is plugged in all 4 are making a good connection and that should correct this issue
the brown colored is the bad connection of the terminals which will cause this problem
if by an odd chance you can not get the terminal closed off enough or it still will not make good contact and or does this again you will need to replace the fuse box to correct this problem
but most can be fixed by tweaking over the center of the female terminals in the box
if it still is doing this the box has to be changed
the witness marks on # ***** terminal is the terminal or connection issue since the source of a bad connection causing too much heat is the burn / black or brown marks
nothing else can be
