LIFTGATE MOTOR
Vehicles equipped with a power liftgate, utilize a liftgate gear motor assembly. The gear motor assembly consists of a DC motor, hall effect
sensor, engage actuator, full open switch, lift gear, aluminum housing, drive gears and wire harness. The gears and motor portion of the assembly
provides the power and torque required to open or close the liftgate under the worst case conditions. The hall effect sensor is used to provide the
liftgate control module with a speed reading, which is used to monitor the resistance of liftgate travel. This speed reading also allows the power
liftgate control module to detect obstructions and move the liftgate accordingly The engage actuator is used to toggle between power open/close
mode and full manual mode when desired. The full open switch is used to let the power liftgate control module know when the liftgate is
approaching the full open position.
Serviceable components of the power liftgate gear motor assembly are the complete gear motor assembly motor and wire harness, lift gear and
control rod, engage actuator, full open switch and the transverse bracket. Refer to additional information in this group for more component details.
With the push of a power liftgate command switch (liftgate closed), the power liftgate control module will signal the latch assembly to release the
door from its primary closed and latched position to the released and movable position. The liftgate motor mounted, engage actuator then engages
the liftgate motor assembly, which moves the liftgate into the open position. The liftgate motor provides the torque and power to move the door to
its full open or closed position (Refer to ELECTRICAL/POWER DOORS - OPERATION) for additional information.
