The indoor blower scroll structure includes integrally formed vent and exhaust port walls with associated doors attached thereto. A single actuator mechanism is also attached to the scroll structure and is mechanically linked to both doors to thereby provide a single and reliable actuation assembly, all of which is mounted on the scroll structure. In a preferred embodiment, the actuator comprises a single, lever actuated cam which directly engages levers on both the vent and exhaust doors.
