Well,
as of my last drive in the van (just now) my fan which earlier silently
blew fuses is now a very load, monster of a  fan that has some serious
issues.  So no rewiring for me after all.  Oh well.  I guess I'll have
to be tackling the dreaded dash job at some point.

How long should this job take me?  And are all replacement fans the same?

Thanks for all the help,
Wes
