Ok quick break from tech to report on a known car problem and the fix. I have a 2010 Ford Escape, and put the bigger side of the 40/60 split rear seat down to fit a table in the rear. When I went to raise it back up, it wouldn’t move more than an inch or two.
After some investigation I determined the problem was that the middle seat belt, which actually retracts into the top of the seat, had retracted completely and then locked up, stuck.
I spent some time trying various things to get it to let go. I even had half the material off the seat so I could see up to the area where the retractor was mounted. Nothing I tried did anything but make it tighter.
I turned to the Internet, and found out this is a known problem with these Fords and perhaps other models going back several years. Argh! For instance, http://www.venturerider.org/forum/showthread.php?t=60783
Then I found a site that seemed to have some solid advice - http://www.fixya.com/cars/t6637034-ford_escape_middle_rear_seat . This turned out to be fix for me.
Basically take out the 6 bolts holding the seat backs down (2 on each side and 2 in the middle). Then you can get to the Torx bolt that bolts the seat belt to the floor. Then take out the 60 part of the seat back completely, turn it right side up, click in the latch on the side, and the seat belt should retract normally with a couple of pulls. Then just put everything back together the way it was.
Save yourself wasted time trying other methods. They are right when they say this is the only way that works. And once you figure it out, it’s not that hard. Good thing, because I’ve got a feeling I’m going to be doing this again and again.
