Someone else suggested the no heat when stopped situation is normal
during cold weather because the coolant temp drops.  In my experience,
and that of a good many others, Vanagon usually runs cooler when moving
than when idling, due to increased air flow through the radiator.  But,
if the water pump is moving fluid poorly, perhaps the radiator and
coolant pipes would have stagnant coolant.
