Heated mirrors in Florida??!!!
Do you need them to dry the humidity off the mirrors to be able to see?? :-laf:-laf
Don't laugh *too* hard! It might not happen often in Florida, but if you drive into a region of high humidity where the dew point is higher than the temp of the mirrors, vapor can condense instantly on the mirrors. And windows if the A/C is plenty cool. It's happened to me often enough.
