There is a little metal clip that holds the heater cable on the body of
the front heater valve.  That clip is likely rusted and fell off.  The
cable therefore just moves freely and is not able to close the valve.
Could also be the valve arm rusting off, but more likely the clip.

Subject: Heater always blows hot

My 84 Vanagon seems to always blow hot air from the heater vents, I have
to
move the top two all the way left, the #3 all the way right, and the #4
all
the way left, to minimize the air flow.

If I move all 4 to the left, I get very warm air (almost hot), coming
from
the floor vents.

Never had this problem before?

Thanks in advance for the guidance!
