the blower fuse is NOT located inside the main fuse box. it
is a "strip" fuse in a little black box (about 1.5x.5 inches) located forward of the main fuse box. it is very common for these fuses to get stress cracks which you cannot see, but still causes the blower to come on and off
at random. you can get this fuse at a MB repair shop; parts
stores do not have them. might as well get a spare.
