I have a 2013 Escape SEL Ecoboost 1.6L FWD with 121K. Two days ago when my wife tried to open the rear door on the driver's side, with would disengage the rear latch, but the hinges would not open on the front of the door. I investigated the other rear door and I am wondering if the arm that goes into the door midway down could be the problem? I am guessing it is connected to the internal mechanism to allow the door to open. Unfortunately, my children have been rather rough with the outer door handle and I figure that this is part of the problem. Any tips or suggestions on how to diagnose and repair the problem without breaking the door? Thanks!
