If the one-touch (auto up/down) windows stop working on your Vauxhall Astra K (Mk7, 2015–2021) — Opel Astra — usually after a flat or disconnected battery, the window motor has lost its learned end-stops and anti-pinch reference. Re-teaching it takes seconds per door, no tools.
Why It Happens
The window controller remembers the fully-closed position so one-touch can stop correctly and the anti-trap can work. A power interruption clears that memory, leaving only hold-to-move operation.
How to Re-initialise a Window
- Sit in the car with the door closed and the ignition on.
- Pull the switch up to fully close the window and keep holding for about 2–3 seconds after it stops.
- Release, then press the switch down to fully open and hold a moment at the bottom.
- Pull up again to fully close and hold for a couple of seconds at the top.
- Release and test one-touch up and down — it should now run on its own.
Repeat for each affected window using its own switch.
If One-Touch Still Doesn’t Work
- Hold a little longer at the fully-closed stop — the controller needs to register the top limit.
- Make sure the door is shut and the battery is healthy during the learn.
Frequently Asked Questions
Why did my Astra windows stop going up automatically?
A battery disconnect or flat battery wiped the learned position; re-initialise to restore one-touch.
How do I reset the auto window on a Vauxhall Astra?
Hold the switch up to fully close and keep holding 2–3 seconds; if needed, fully open and fully close again, holding at the top.
Do I have to do every window?
Only the ones with one-touch — re-teach each from its own switch.
Do I need a tool?
No — it’s done entirely from the window switches.
