The 1969 to 1971 C cars use a vacuum operated heater control valve that looks like the picture below. I tried opening my service manual on my CD but the CD isn't working so I want to pick the brains of others here in the short term.
Here is the question, does the valve need vacuum to keep it open, or does vacuum shut the valve?
