As far as I know, your AC is kicking in automatically when you select defogger, so the system is cooling the air just as if you were using your air-conditioner though the vents.
It looks like there can be a difference of up to 5 m/s between cloud velocity and wind velocity (http://journals.ametsoc.org/doi/abs/10.1175/1520-0450%281976%29015%3C0010%3AWEFCMP%3E2.0.CO%3B2 ).
Clouds move with the wind, so the cloud velocity is just the wind velocity. The recent storm in the Philipines reached wind velocities of 200 mph, though the higest speed reported is apparently 253 mph. The fastest moving clouds known are on Neptune, where the winds reach 1340 mph.
I think you have a misunderstanding of the technical terms vapor pressure, boiling and partial pressure. Vapor pressure or better equilibrium vapor pressure is the pressure at which an equilibrium is reached between evaporation and condensation at the liquid surface. Usually it is a function of liquid temperature. E.g. water has a vapor pressure of about ...
