yes, ford had a period when they set the blower to always run a little, even with the switch in the off position. was a good idea in some ways, as it stops the cabin misting up.

always annoys me as an HVAC engineer when i see people driving about with their windows dripping on the inside cos they've switched the blower off the damn thing has an infinitely variable temperature setting between cold and hot so that you can get the right temperature for you. why turn off the airflow?
