have you taken out the fuse or just visually inspected it in place?

sometimes, some oxidation forms on the contact points of the fuse and although still good, may just need to be cleaned (but since they are so cheap, replace them with new ones).

because the 201 fusebox is so difficult to access, I just press the fuse against the connector, forcing it to slide, clean the contact area and reseat itself.

hope this helps ...
