When you change the battery the windows should still work. But not with my 2016 Outback. Following the battery being replaced, the driver switches commanding all 4 windows failed to control the front passenger window. Upon reaching across the passenger seat, I found the passenger door switch still was able to command the window down. This proved the window motor and associated circuitry still worked normally. It seemed like swapping out the battery in the engine bay induced this niggling failure.
Fortunately, I was near my Subie dealer. The service manager took a moment and showed me how to fix it: From the passenger door, roll the window down, holding the passenger-side switch for an additional 3 seconds. Then pull up on the switch to roll the window all the way up, and keep the switch up for an additional 3 seconds.
Following this reset, the driver’s switches were able to command the passenger side window once again.
As far as touting the superiority of reading my owner’s manual, I doubt doing that would have been as efficient as stopping in at the dealer. That book is buried inside the spare tire. Had dug it out, I flipped to the index, located where this oddity is addressed, would it have fixed this issue as well? I doubt it. At least for me it was far quicker to stop in and the dealership and get shown how to do it.
Why it is that this vehicle is made with a known and persisting defect without being corrected seems a bigger issue than faulting consumers for not consulting their too-large owner manual over this unexpected oddity.
