Do I have two AC systems? I see some posts talking about an auxiliary system, but I can't find anything regarding my vehicle. Can anyone shed some light?

Yes, the auxiliary unit is basically a duplicate of the front HVAC unit, just smaller. The auxiliary system has its own Evaporator and expansion valve (and heater core, for heat)That stuff is there, but are there other mechanicals? I see some posts with 1.37lbs of R134 in the front and 2.00lbs for the rear. That is the part I don't understand. Is there a second evaporator somewhere. I saw a different type of SUV, unfortunately I don't remember which one, but it had a second evaporator in the cargo area under panels behind the wheel on the drivers side.
