The back door doesn't open. I hear a clicking noise when I push the button, but the door won't unlatch. It is a 2012 Ford Escape.
The problem is the latch actuator broke and needs to be replaced. The replacement part number is 9L8Z-7843150-B. I found genuine parts on Amazon for ~$100 or a generic part on Ebay for ~$50. This part will fit 2010-2012 Ford Escape & Mercury Mariner. Here's a video on how to do the repair: https://www.youtube.com/watch?v=BKXGgQYXXO4
