What do each of the actuators do?

I am trying to figure mine out, and a PO has plugged a brown line and the "AC Mode" actuators have gray lines run to them.

Do the "AC Mode" actuators switch between heat and AC, or between defrost and AC? Or between fresh air and AC? Other?

Where are the other actuators located? The one with the yellow and blue hoses; is that one inside the blower box?

Where is the "Heater Mode" actuator located?

Where is the "Outside Air Recirc" actuator located?

Where is the "Water Valve" actuator located?
