Thanks for this info.It has it's own system, a separate evap that's tied into the main AC freon system. Part #12 in the attached PDF.
Past winter I took a road trip and hoped to have cold drink at the ready on the way. Realized then that I had to have AirCon on to use the cool box. Temps outside were mostly in the teens, so no, wasn’t doing that. I figured it was just blowing some frigid air on/in the box to achieve the amazing “cool” box feature. Seemed akin to a subway grate in NY being called a street warming hut option. Didn’t try turning AC on, but setting interior temp in the 70’s - I was already getting poor gas mileage in the deep freeze drive and I’m guessing this would only have rubbed salt in the wound. I was stopping to fill up frequently enough and could just buy “a cold one” at the gas station if I needed.
