what happens with feed to fuse is that the solder around fuse holder blade cracks around pin on pcb, you may need a magnifying glass to see it,but if you are very careful you can remove all parts on fuse box [with it out of vehicle] making sure you have made a diagram of where they all fit.carefully detatch outer covers to get to the blade and re-solder it -have done this on several occasions with 100% sucess.
