My old Fiat Marea Weekend had instructions for defogging the windshield on the inside of the driver's visor:
- Turn the blower on max
- Turn the heat on max
- Turn the recirculation off
- Put down the visors (emphasis mine)
I can come up with reasons why this should help and I can come up with reasons why keeping the visors up would be better. So which is it?
Does putting down the visors indeed help in defogging the windshield?
