1971 Mustang Old Air Products A/C install Part 2.5: A look at the Old Air unit assembly

In this video, I take a few minutes to show and describe to the best I can about the Old Air Products A/C and heater box assembly unit in greater detail. This is a good video to understand how this thing is made and how it's supposed to work.
