Auto Window Up: rear drivers works at times...

[Leeford]

I've had this issue since May. I can reprogram it by doing the up and hold. This does resolve the issue for the time being but it will stop without notice. I can't figure out the issue. I called ford and they will want to see it in two weeks...if it's still acting up.
Any ideas out there?

just guessing but there may be a bind in the mechanism or window track that fools the brain that the window is blocked. My wife's Escape did that and some silicone spray in the window track cured it.

There's separate learning for bounce-back and auto-up/auto-down stop points. I didn't realize they were wiped with battery disconnect (and I assume under-hood fuse-block disconnect).

I went to the dealer and they scanned the OB. They corrected what ever was going on...so far so good.

I wonder if there was a behavioral tweak made to the logic in the associated control modules' firmware that made it into later editions, but didn't warrant a TSB of its own. Perhaps the default torque-limit sense level during auto-close was too close to "typical" drag of a window in the wild, or similar.
