Reinitialise the Electric Windows

Last updated: June 7, 2026

After the battery on your Alfa Romeo Giulietta (2010–2020) has been disconnected or gone flat, the one-touch function on the windows often stops working — the glass only moves while you hold the switch. Re-initialising each window restores it in seconds, with no tools.

When You Need This

Each window motor remembers its fully-open and fully-closed positions, and that memory is wiped whenever the 12 V battery is disconnected or runs flat. The symptom is a window that won’t auto-close or auto-open on a single press. The fix is a quick relearn from the window switch.

Re-initialising a Window

1. Pull and hold the window switch in the CLOSE direction until the window is fully shut, then keep holding for a moment after it stops, and release.
2. Press and hold the switch in the OPEN direction until the window is fully open, then keep holding briefly after it stops, and release.
3. The window is initialised — check that one-touch up and down both work.
4. Repeat for each window that has lost its one-touch function.

If It Still Won’t Auto-Close

• Hold the switch past the end stop in each direction — the motor needs to feel the limit to learn it.
• Make sure the glass runs freely — a sticky or iced channel can stop the relearn completing.
• Persistent fault? A window-module or switch issue can store a code — look it up on autodtcs.com.

Frequently Asked Questions

Why did my Giulietta windows stop auto-closing?

The one-touch memory is cleared when the battery is disconnected or goes flat — the relearn restores it.

Do I need any tools?

No — it’s done entirely from the window switch.

How long do I hold the switch?

To the end stop, then a moment longer, in both the close and open directions.

Do I have to do every window?

Only those that lost one-touch, though it’s quick to do them all after a battery job.
