Ya larn somtin new ever day.  Hummph!  I sit corrected (a little 
more warm too boot!)

Indeed, the top lever in my '80 Vanagon DOES control location of 
floor heat.  Right = defrost, center = front only, left = front and rear

As to adjusting them, I suspect that the adjustment is in the 
clamping location of the cable sheath behind the dash.  Loosen and 
changing the position of the sheath will change the relative position 
of the business end of the vent door relative to the cable itself, thus 
allowing some adjustments.

WRONG, WRONG, WRONG I admit.
I can get front heat, without heat to the rear with lever in center position.
Sean, it could be that there is something inside the vent where the door 
is, holding it open.

Above is wrong, too, as you can figger out by now.
The below stuff may still apply.
