OK.  Spent most of last night removing everything forward of the front
floormats.  Have the fresh air fan out and on the table. vacuumed the previous
resident's debris out and got the fan to spin.  Question is:  is it worth
attempting a rehab or do I just buy a new unit?  who's been here and what have
you done?

also, btw:  all 4 sliders on the "climate adjust"  are supposed to activate wire
cables; three open or close vents and one, the second from the top, activates
what appears to be a valve in the heat exchanger line.  on my '87 that cable had
broken, and the lever always had a mysteriously easy action as a result.  I
always assumed the lever activated an electrical switch somewhere,and though it
never felt like it was doing anything, I was always scared to look into for fear
i'd unleash an electrical demon under the dash.  with everything out and in the
open, the under dash electrical frontier aint all that scary a place.

looking froward to a defroster this year,  Curt.
