Have the same exact problem with my 1986 560... the blower's working now and I haven't replaced the fuse with the external one because I've kept replacing the fuse (by using the copper filament of the blown fuse and sticking it down into the melted cavity to make a connection since the lower contact is pretty much gone) and so far its blowing. I'll go out in the parking garage and get the part # for the external fuse (that I haven't installed since its still blowing) and it does have a 30 amp strip fuse.
How difficult is it to install this? Can you just remove the top portion containing the contacts to expose the wires or will I end up cutting my wire insulation to access them? I ask because I unscrewed the actual box to lift it and the wires that were secured with the insulation prevented me from lifting it and it looked like I may have to cut it to get to the wire so I put it right back and stuck the external fuse in my trunk until I HAD to replace it and just haven't taken a look at it since. Any help is appreciated and thanks in advance
