Abstract: A method for manufacturing a motor vehicle air flap apparatus for quantitatively controlling a cooling air flow in a vehicle space, the air flap apparatus encompassing: an apparatus frame having a passthrough opening; at least one air flap that extends along a flap axis and is mounted on the apparatus frame pivotably, around a pivot axis parallel to the flap axis or coaxial therewith, between two operational positions providing different coverage of the passthrough opening; such that the method for manufacturing at least some of the components of the motor vehicle air flap apparatus encompasses an injection-molding method; the method encompasses, for the manufacture of at least two components of the motor vehicle air flap apparatus which are connected to one another by positive engagement, an assembly injection-molding step with which one of the two components is manufactured in local positive engagement with the respective other component.
