For the list's sharper minds than mine:

I'm getting full fresh air flow through the passenger side dash vent, but
almost none out of the driver's side.  Pulled the flex tube off the heater
box/blower, and no air flow there either.  I had to patch things back up,
and now need to make the vent work.

My Bentley does not have a section on the heating system, though it does
have a bunch on air-cooled and a bit on diesel heat.  I'm anticipating
removing the instrument cluster, pulling the flex hose, and finding
something to dig around inside the heater box outflow tube.

Anyone have any hints or gotchas on doing this?  Should I expect to find a
rodent in there (no smells)?
