Abstract: A vehicle air handling system includes an air duct housing, a particulate sensor, a first air blower and an electronic controller. The air duct housing has an air inlet and a passenger compartment vent. The particulate sensor is configured to detect a particulate level of particulates in the air duct housing. The first air blower is disposed in the air duct housing to move air within the air duct housing. The electronic controller is operatively coupled to the particulate sensor and the first air blower. The electronic controller is configured to operate the first air blower to reverse an air direction of the first air blower away from the passenger compartment vent upon detection of the particulate level of the particulates in the air duct housing being equal to or greater than a predetermined particulate threshold level in the air duct housing.

Abstract: A vehicle fan shroud de-icing assembly includes a vehicle radiator, a fan shroud installed to the radiator, a fan and a heat providing member. The fan is installed to the fan shroud adjacent to the radiator and is configured to selectively move air between heat transferring fins of the radiator. The heat providing member is attached to one of the radiator and the fan shroud. The heat providing member is positioned and configured to provide heat to the fan shroud and/or radiator in order to melt ice, show and shush retained within the fan shroud or on surfaces of the radiator.
