After the 12 V battery on a Ford Puma (2020–present) has been disconnected or run flat, the one-touch windows often stop behaving — they’ll only crawl up while you hold the switch, and the auto up/down and anti-trap drop out. The motors have simply lost their learned end-stops. Re-teaching them (Ford calls it a “bounce-back relearn”) takes under a minute per window and needs no tools.
Why It Happens
Each window motor remembers exactly where the glass reaches the top and bottom so the auto feature knows when to stop and the pinch-protection knows what’s “normal.” Cut the power and that memory clears, so the window reverts to manual-only inching until you re-teach it.
Re-initialise Each Window
Work one door at a time from its own switch, with the ignition on. Ford’s recommended sequence runs within about 30 seconds:
- Close the window fully if it isn’t already.
- Press and hold the switch in the OPEN direction until the glass is fully down, then keep holding a few extra seconds, and release.
- Pull and hold the switch in the CLOSE direction until the glass is fully up, then hold a few extra seconds, and release.
- Test one-touch up and down — a single tap should now run the window automatically.
Repeat for each window that lost the function.
If One-Touch Still Doesn’t Return
- Do the whole sequence again — the extra hold at each end is what writes the limit; rushing it is the usual reason it doesn’t take.
- Make sure the glass reaches the true top and bottom — grit, ice or a sticky run can stop it short and spoil the relearn.
- If a window keeps bouncing back down as it nears the top, that’s the anti-trap reacting to an unlearned limit — finish the relearn and it settles.
Frequently Asked Questions
Why did my Puma windows lose auto after the battery was disconnected?
Cutting power wipes the stored end-stops, so auto and anti-trap switch off until each window is re-taught.
The window only moves while I hold the switch — is that the same fault?
Yes — that’s the “limits lost” state. The open-fully / close-fully hold routine restores one-touch.
Do I need any tools or a scan tool?
No — it’s done entirely from the door switches with the ignition on.
Should I do this after every battery job?
Yes — run it alongside any battery disconnection or replacement so the windows come back to full function.
