Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Description & Operation
The door lock actuators, including liftgate, are controlled by two-way switches. Switches are combined with the power window switches (if equipped). To lock the doors, push down on driver or passenger switch, mounted on door panel. To unlock doors from inside the vehicle, push upward on either switch.
The power door locks do not lock or unlock the doors from the outside the vehicle. Insert the key into the lock cylinder to lock or unlock each individual door.
The door locks are operated by reversible motors that receive voltage from fuse No. 13 in the fuse panel. Voltage is applied to the drivers side door lock switch and the passenger's side door lock switch through the No. 9 fuse. With the drivers side door lock switch in LOCK, voltage is applied through the switch to the door lock relay coil. The relay coil is energized which closes the circuit from the circuit breaker to the lock motor. The motor is grounded by the unlock relay.
The passenger's side door lock/window switch operates the same as the driver's door switch. The voltage and ground paths are reversed to unlock the doors.
The power door lock operates with battery power and, therefore, is independent of the ignition switch.
