Rear door lactch will not open but other doors do

Rear door latch will not open but other doors do using key remote. How do I get the rear lift gate door open?

I have the same issue on my 2002 Escape. I hear the cylinder motors engaging on the doors but not the liftgate so all I can assume is the wiring loom on the passenger side upper corner of the liftgate needs attention. That is where the wiring is for the door motor that releases the window and gate. I will post again after I solve this. 6/28/2009
