2009 Jeep Liberty
All four doors and liftgate lock when the lock button is pressed, but only
driver's door unlocks when the unlock button is pressed. Nothing audible
from passenger doors or liftgate when unlock button pressed. Doesn't matter
if using fob or buttons on door.
On my old jeep it was 1 click drivers door 2nd click passenger doors 3rd click rear hatch, but if the inside button is also doing the same thing there could be an error in the BCM program for the door locks. Has the vehicle even experienced a voltage loss or have you jumped anyone? If so this may have been the cause. Call you local jeep dealer and see what they charge for testing the programming of your BCM, it might need a reflash.
Had same trouble with our jeep. Saw on utube how to reset locks. Sounds crazy but it fixed our problem. Put the key in the lock on the hatch. Turn the key left, right,left. Then remove. Worth. A try.
