Bottom passenger Vent

My '68 C-20 has factory air.
This vent on the passenger side is always open,. I assume it's controlled by the air conditioner controls?

Re: Bottom passenger Vent

I'm pretty sure everything is hooked up. I'll check.
So, when is it supposed to be open or close?

Re: Bottom passenger Vent

Great picture, so that's where the missing spring should go.

In the picture you posted there is not a hose hooked to the vacuum port shown Sorry I just looked again and there is a hose on it. It should be open when the upper lever is on inside air and closed when on outside air
