Huh.  Checked the owners manual for the '86 Wolfsburg and it also say
25A.  I remember a time when it got very bad in terms of squeal,
based on weather and a time when the switch didn't do anything.  So
it may have seized in very hot or cold and blew the fuse and is now
OK to at least spin again.

Owner's manual for '89 says 20 amp.  The blower in its shroud running
in free air (maximum-load condition) draws 12 amps from a
fully-charged battery, so if there's enough drag that it's blowing a
20 that's a real issue.  However I've seen one of those motors seize
and smoke without blowing the fuse...but that was a short-term
issue.  Haven't got Bentley nearby so can't be more helpful just now.
