摘要： A door actuator for an HVAC system of a vehicle includes a driving motor having a worm wheel and accommodated within a casing. An actuating gear has on an outer circumference thereof a worm thread that engages with the worm wheel, with an actuating thread being provided on a surface of the actuating gear. A change gear unit is hinged to the casing and rotatably engages with the actuating thread part. A solenoid unit rotates the change gear unit in a first or second direction. A first driving gear is provided at a predetermined position of the casing to engage with the change gear unit rotating in the first direction. A second driving gear is provided at a predetermined position of the casing to engage with the change gear unit rotating in the second direction.
