Hello and welcome to JustAnswer!

If the liftgate is the only thing that doesn't unlock then the problem is either going to be wiring or the liftgate lock actuator. The liftgate is on the same circuit as the rear door power lock actuators so if they do unlock at the time the liftgate doesn't, you know that signal is actually being sent.

What will need to be done is remove the liftgate trim panel and use a test light to see if the actuator is being powered when pressing the lock and unlock buttons. If not then there is a break in the control circuit, if there actually is power but the actuator does not move then it has failed.
