The arrangement includes a fan (7) which is arranged in an air-conditioning channel system (1), and a heating arrangement (9) which is arranged in the channel system and which heats air which is absorbed and/or furthered by the fan, under application of motor cooling water as a heat source. A foot outlet (12c) is provided, through which air is submitted in foot height, and a defrost outlet (12a), through which air is submitted along a windshield (30), are arranged both at a downstream side in the air-conditioning channel system. Opening and closing devices (11a, 11c) are provided, which open and close the foot outlet and the defrost outlet, and a number of PTC heating devices (13, 14) are arranged in a downstream side of the heating arrangement. Some PTC heating devices are arranged at the foot outlet, and the remaining PTC heating devices are arranged in a passage, through which air is conducted from the heating arrangement, both to the foot outlet as well as to the defrost outlet.
