Abstract
A defroster system for a motor vehicle is disclosed having air discharge openings in the dashboard which enable warm air to flow upwardly and impinge against the windshield. To ensure that the lower portion of the windshield is also being heated, and to prevent the windshield wipers from becoming frozen onto the windshield, secondary air ducts are provided which extend from the defroster duct into an open space which is disposed inside the vehicle in the proximity of the lower edge of the windshield and ahead of the windshield. The secondary air ducts are created by depressions formed into the lower wall of the defroster duct.
