You didn't mention whether it was the Brown, Blue or Grey interior.
I have found that my air vents don't blow air when closed either, but that
might be a problem that only occurs in the brown interior vanagons...  Try
pulling the vents from the dash and drilling 3 or 4 1/2" holes through the
plastic flaps.  I believe that it's these flaps that are causing the problem.
Best of luck.
