My wife's Edge is at the Ford dealership now for this issue and they just told us it's going to be $420 to replace the latch. I tried spraying contact cleaner as instructed in the video but it didn't work. I'm hoping "Ford Service" might be able to chime in with a solution that will, at least, lesson the blow of this $420 price tag.
We have them on hold right now until we can decide or get some help. They need to know by 2:30 if we want to get the car back by tomorrow.
