Now that the wet, cold weather is here I decided that my heater wasn't blowing very well, even with the blower on.
After taking the fan out of the car ('65 Midget) I realized that when I "opened" the control I had overshot the open position and gone clear to "closed" again.
What I found is that the shut-off air valve needs to be set to full open when the fan unit is not there, so you can see the flapper.
Now that I have it fully open when I think that it is the heater/defroster actually works!!
