Heater fan blows all the time
Oldspowered,
I'm not sure if your heater set up is the same as the mid 60's cars, but if so, here is a link for a heater box rebuild that will help you get the box down so that you can look at the fan and its connections:

Since your fan runs constantly at high speed, it sounds like the resistor is either damaged or bypassed. Depending upon your set up, you should see the heater motor speed resistor mounted on the heater box. If you look closely in Part 15 of the article, you can see the fan motor resistor to the right of the heater core and below the fan (the resistor is a coiled spring inside the box, and the 3 prongs for the connector stick up from the box).
Hope this helps.
