Very happy to hear you found something. As I said, Cadillac has their own way of doing things. One word of warning though. Before you put everything together, ... If that is indeed the AC system drain tube, the pan or box will probably take a long time to fill up. I don't think a week's worth of commuting will do it unless it's really humid where you are.
The AC system is only expected to lower air temperature by around 20 degrees. The real comfort comes from the humidity condensing on the cold evaporator in the heater box. That condensation drips into a pan and should run outside onto the ground. No water should stay in the pan because mold would become an issue. By "done the trick" do you mean water came pouring out? I hope so.
Also, when you get to the end of your commute, peek under the car, between and a little behind the front tires. If you see water dripping there, run into work with a smile on your face and buy everyone coffee!
