1. A forward view mirror system for a motor vehicle comprising first and second mirrors sequentially arranged to provide the driver with a view of the road ahead, said first mirror being located above the driver'"'"''"'"'s head in a forward view chamber and positioned to reflect an image of the road in front of the vehicle to said second mirror, said second mirror being located directly in front of the driver and adjustably mounted so that the image of the road reflected by said first mirror will pass through a clear glass panel which forms the lower forward section of said forward view chamber and will be reflected by said second mirror to the eyes of the driver, a high pressure air chamber located above said forward view chamber and including a forwardly directed duct inlet which collects air with precipitation during the forward movement of the vehicle and directs the precipitation to a drain duct located in the lower aft wall of said high pressure air chamber, said duct inlet redirects moisture-free air through a high velocity air chamber to a duct outlet located above the forward view opening of said forward view chamber, said duct outlet being shaped to direct moisture-free air from said high velocity air chamber downwardly in front of said forward view opening to create an air boundary layer which prevents precipitation from reaching said first mirror, a reciprocating wiper consisting of two wiper blades which horizontally scans and removes all moisture from the reflecting surface of said first mirror and surface of said clear glass panel within said front view chamber.
