Even with the top down the screen often suffers from heavy misting so with one press of the button, problem solved!
Should not do this. Water collecting in the heater system? A pinhole in the heater matrix? Wet carpets? The moisture has to come from somewhere and misting requires a flow of damp warm air over a cold windscreen so depending on whether the misting is inside or outside I would wonder the source of the dampness except maybe for advection fog in autumn.
