Have you checked the position of the flap that controls air inlet when
set to a temperature that matches the interior, versus one that is
wildly off and would trigger the flap closing?

Also, have you checked for leaves/debris, and clear drains, behind the
firewall and under the cover?  The leaves/dirt retain moisture, and a
clogged drain will let water stick around.  Lots of leaves will hinder
airflow.  Someone on the 200q20v list had a similar problem and found
that his condenser was covered in junk, restricting airflow into the
car.

I wonder if the rear vents under the back bumper (assuming the C4 has
them) ever stick and cause this sort of problem...probably not.
