11. A heating, ventilation, and air-conditioning (HVAC) assembly for a motor vehicle, the assembly comprising:
a scroll housing subassembly comprising a scroll housing and a blower motor;
an evaporator housing subassembly; and
an air inlet housing subassembly,
a first securing element, the first securing element being distributed on the scroll housing subassembly and the evaporator housing subassembly and configured to detach at an extraction position;
wherein the scroll housing subassembly is configured for rotating from an installed position to the extraction position,
wherein the blower motor is rigidly attached to the scroll housing, thereby resulting in a joint rotation of the scroll housing and the blower motor when rotating the scroll housing subassembly,
wherein the joint rotation is about an axis through the blower motor,
wherein the scroll housing subassembly is configured for removal from the HVAC assembly at the extraction position,
wherein the scroll housing subassembly reaches the extraction position by rotating axially in a direction orthogonal to a direction of extraction, and
wherein the scroll housing subassembly is the only subassembly removed from the HVAC assembly for servicing the blower motor.
