My brother does not understand how air conditioning works. He thinks turning the temp down to 60 an the truck will cool it faster than at 68 in a hot day.
For my 2019 Chevy, that is 100% true. Unlike the house where the a/c is an all or nothing option, the truck will blow air the temperature shown on the thermostat.
If you get in the truck in a 100 degree day it will not cool off the interior any faster if the temp control is set to 60 or 68. If it is set to 60 it will eventually cool to that temp but it will not reduce the temperature any faster from 100 to 68.
