This "how to" is great. I just replaced my driver side latch and without this tutorial it would have been a much harder job. All said it took about an hour and a half. I do find it unacceptable that a vehicle with 20k miles already has this type of problem. Unfortunately for me I have a 2011 and it's out of warranty. Ford should defiantly redesign the switch. I have the feeling I'm going to be doing this same thing again in another 20k miles. I'm a nerdy engineer so I disassembled the latch to see what the issue might be. I thought that the switching contacts might become corroded but once it was disassembled it's not a corrosion issue as it's a completely sealed unit. (in theory the WD-40 trick shouldn't work). I cut the switch in half and the actually switching components and springs are microscopic, my theory is that the small switches just can't handle the repetitive switching that the doors see and eventually they bend and don't work. below is a photo of the switch and the internal switching contacts.
