It's been put to me by a list member that there's supposed to be a fan
running from the back heater in my 85 Vanagon. (who knew?) Front fan works
(if not a little noisey but no one's perfect and i'm not taking off the
dashboard...not yet anyways)

What's the best way to find out what's up? I mean after the fuse. Seems to
be heat coming..but no fan sound when i turn the knob for it.
