Answers :

The door locks are controlled by the vehicle security module (VSM). It gets power from fuses 30, 5, 6, and 40 in the central junction box (CJB). You say you checked these and all are OK. Therefore the problem must be in the door lock actuators, the door lock relays, or the door lock switches. I doubt that all of these are defective, so the VSM may be defective.

The liftgate is controlled by the power liftgate module (PLM), althogh the motor in the liftgate glass actuator is controlled by the VSM. The PLM gets power from fuses 105 and 5 in the CJB. If the PLM is assumed to be OK, the source of the problem could be the liftgate unlatch motor, the liftgate cinching motor, the L/R liftgate obstacle detection strips, the liftgate home position switch, the liftgate fork bolt/detent switch. or the power liftgate open/close switch
