Thanks Mark,

You "nailed it"       It is not so easy to see that a "bare metal strip"
is in fact the fuse when it is no longer there. Bentley shows a fuse but
it was not clear based on the fuzzy images what to look for.

I confirmed that (after making the connection that the fuse provides)
the blower works in the 2 high settings just fine !!

So the obvious question now is:    Where to get a replacement fuse ?
This has to be a dealer item ??
