heater control question

2 of my cables have broke away from my heater control unit and i am going to replace it but not with the original unit. I have one question. Why is the right vent gate driven by a vacuum motor? I was thinking about using a cable to open it or leave it open all of the time. Had anyone done something similar?

No idea its a good question for the Jeep engineers.

I replaced mine with a used unit on Ebay. Wait around for one cheap it was easy to replace and everything works.
