63 heater

[John Fahnestock <jdfahnestock@xxxxxxxxxxxxx>]

I need some help figuring out how the heater is supposed to be plumbed in 
the 63.  Evidently the control valve failed and the heater is now 
directly connected, making for very uncomfortable summer driving.  I am 
going to get the control valve rebuilt/replaced, but there is another 
vacuum actuated valve mounted on the passenger fender that I don't see in 
the FSM.  Is this supposed to be there?  It looks like the hose may have 
connected through this valve before it went to the control valve on the 
fire wall.
