Cockpit Heating System

[k7ujx1]

I haven't seen to any on ask about the Original dash heating, I have read
the manuals but I am still not sure. mine has the deflector that rises up
from the floor with two outlets on it. Is this unit supposed to blow cold
air all the time? and what about the air outlet on the drivers side next
to the window? I don't get any thing out of this?
Checked all the hoses all seem to be ok Vacuum tank is not a problem
selector and the connections all seem to be functioning like the manual
say's. Where did the GM engineer go for lunch the day he designed this?
Any help will always be appreciated.

Has anyone a nice pictorial of how the various vacuum lines work and what
they do, and where they go. I have one that leaks, and there is probably a
place in the manual that explains it, but my coach is in Calif and I am
still in Albuq and I would like to study up on the system.
thanks in advance.

Gary, check to see if the PO installed a shut off in the line. It
probably would be under the front hatch, left side. Some owners have done
this.
