Question A/C vacuum actuator kick panel question

I am restoring the interior on my '70 C-10, 402 with factory A/C. The passenger side outside outside kick panel air vent appears to be controlled by a vacuum actuator versus the driver's side that is controlled manually by a pull-type knob.

First question...is this correct? I am assuming the passenger side vent is somehow controlled by the 4 season A/C system? Can anyone tell me how it actually works?

Thanks for any help anyone can provide.

There is a vacuum valve on the back of the controls and when you push the lever to inside air it closes the door on the passenger side. There was just a thread on this last week so you might be able to find it and I posted the vacuum hose routeing on it

Get out and drive the truck this summer and have some fun!
It sucks not being able to hear!

LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.

Perfect, now I know how it works so next step will be to see if it's working properly. Thanks again.
