What should I be thinking about to resolve this?

You need to have UV dye put into the AC system so a tech can possibly find the leak using an ultraviolet light, most leaks can be easily fixed and the cost will not be real bad but still not cheap.....as long as it's not a leaking evaporator, if it's the evaporator leaking the entire dash and all components, electrical. duct work, reinforcements, etc. behind it has to be remove to gain access to the housing it is in, very labor intensive, VERY, VERY expensive.
I will keep my fingers crossed for you that it's not the evaporator leaking.
Just to give an idea of what it take here's a link where it had to be done on a KIA Sportage which is very much the same as what has to be done on our T4Rs.

IF it is the evaporator and you choose to get it fix, also replace the heater core while doing the evaporator as they are both within the same housing and you don't want to do the same job later if the heater core starts leaking.
Both the evaporator and the heater core parts run around $60 to $100 each depending on where and what brand you get, OEM will be a lot more well over $200 each.
Rockauto sells a Denso brand evaporator which is as close if not the same as what you would get from Toyota for around $85, they have 4 different heater cores brands but none are the Denso brand.
