Power Liftgate Drive Unit - Description
DESCRIPTION
Vehicles equipped with a power liftgate system, utilize a power liftgate drive unit. The drive unit assembly consists of a DC motor, chain drive, chain
sprockets, full-open switch, housing/bracket assembly and wire harness. The motor portion of the assembly provides the power and torque required to
open or close the liftgate under most conditions. Internal motor circuitry is used to provide the liftgate control module with a motor speed signal. This
speed signal is used to monitor any resistance of liftgate travel and allows the liftgate control module to detect obstructions and control the liftgate
accordingly. The full-open switch is used to let the liftgate control module know when the liftgate is approaching the full open position.
The drive unit is secured to the D-pillar with three retaining bolts and is connected to the liftgate with the link rod.
The drive unit cannot be adjusted or repaired and if damaged or inoperative must be replaced.See: Service and Repair/Power Liftgate Drive Unit -
Removal for the appropriate procedure.
