1. Since turning off the compressor doesn't defeat the cabin filter, why is the interior air better? (I've never noticed a difference.)
2. The eastern US tends to have much lower humidity in the winter so defogging is normally not required. And if it is, is it that hard to push the damn snowflake button?
I'm reminded of my 1973 Plymouth Fury which featured an A/C compressor which was designed to always be engaged whenever the motor was running. As A/C dropped the 400ci engine's fuel mileage from about 11 to 8 mpg, I wired a switch to turn it off. At least our modern cars have that switch.
