If the car has X units of moisture inside and eventually all freezes inside the evaporator, what is the amount that freezes it to the point of non-operation?

My understanding of the process involves the coldest area of the evaporator, likely most near the inlet from the TXV, freezing the condensate first/initially, and then the process proceeds more and more rapidly as the open area of airflow declines accordingly.
The only recent example, recent being circa 1993-4, was in our 1992 Lexus LS400.
Each instance involved driving up rising terrain, McDonald pass in Mt, I5 in northern Ca. In each the instance the evaporator airflow was practically non-existent by the time we realized the cabin was becoming uncomfortably warm.
It only took a few minutes with the compressor off to return the system to normal operation.
