Power lock switch

The power locks can be controlled by a two-way switch integral to the power window and lock switch unit on the driver side front door trim panel, or a two-way single gang switch on the passenger side front door trim panel. The power lock switch controls the battery feeds to the lock and unlock sense inputs of the high-line Central Timer Module (CTM). The CTM then relays the correct battery and ground feeds to the power lock motors. A Light-Emitting Diode (LED) in the paddle of each switch is illuminated whenever the ignition switch is in the On position.

The driver side power window and lock switch unit cannot be repaired and, if faulty or damaged, the entire switch unit must be replaced. The passenger side power lock switch cannot be repaired and, if faulty or damaged, the switch must be replaced.

Power lock motor

In the power lock and Remote Keyless Entry (RKE) systems, the door and liftgate latch lock mechanisms can be actuated by a reversible electric motor.

The power lock motor is integral to the door latch mounted within each door. A separate power lock motor is used to actuate the liftgate latch.

The power lock motor direction is controlled by the battery and ground feeds from the power lock and unlock relays, which are integral to the high-line Central Timer Module (CTM). The RKE receiver within the CTM can also unlock just the driver door through a separate driver door unlock relay that is located in the relay and fuse block attached to the back of the junction block under the instrument panel.

The power door lock motors cannot be repaired and, if faulty or damaged, the entire door latch unit must be replaced. The power liftgate lock motor is serviced separately.
