To remove the tailgate lock, first open the tailgate and take off the trim panel. If the lock is not working, it can be opened manually by sliding a flat object through the slot in the trim cover from inside the vehicle. Next, release the securing clip and disconnect the operating rod from the tailgate lock, then disconnect the wiring from the lock. After that, undo the retaining nuts to take the lock out of the tailgate. For the tailgate actuator, release the securing clip and disconnect the operating rod, then loosen the retaining screws holding the actuator to the tailgate and slide it out without fully removing the screws. Disconnect the wiring from the actuator as it is being removed. When refitting, reverse the removal steps, ensuring to check the operation of the lock components before putting the trim panel back in place.
