AC HVAC Question?

[Bryen]

The HVAC plug on the end of my switch is leaking, is there any way to trick the system into the MAX AC setting?

Does anyone know where I can order the parts from?

What plug? What is it leaking? Pictures may help
MAX AC mode closes the outside air and recirculates the air.

The multi plug on the right, I will go take some photos of the circular plug, It looks to me like a harness on one end is the switch with a diafram and the just a connecting socket.
