A heating or air-conditioning system for a vehicle has a cold-air duct and a warm-air duct which open out into an air-mixing chamber. One control member is assigned to each of the cold-air duct and the warm-air duct for setting the amount of cold or warm air which flows into the air-mixing chamber. The control member for the amount of warm air is designed as a shutter which includes a plurality of closure lamellae which are arranged next to one another, which overlap one another in the closed position, and which can be pivoted by a common actuating drive. To achieve a less progressive, substantially linear control curve of the shutter in the lower pivoting range, the shutter is designed in such a way that the individual closure lamellae, when they pivot out of their closed positions, open up unevenly sized opening cross sections for the warm air to pass through.
