Default 2002 explorer xls hvac

Blower motor works fine, ac works, temp control works, however if you try to switch from defrost to vent, it doesnt work. I dug into it a little bit and found that the red line going to the vacuum operated actuator is getting no vacuum at all. Which line is the vacuum supply? Is there anywhere i should look specifically for a leak? does anyone have a vac diagram for this? there are five-six lines going into the controller but i have no idea which is which.

Thanks in advance for the help.
