Home/Lancia/Delta/Mk3 (844) 2008-2014/Initialise the Power Windows

Initialise the Power Windows

These instructions apply to the Lancia Delta Mk3 (844) 2008-2014. For other models, please choose your vehicle here.

Last updated: June 10, 2026

If the one-touch (auto up/down) function on your Lancia Delta (844, 2008–2014) has stopped working — usually after a battery disconnection or a flat battery — the windows just need re-initialising. It’s a quick job with no tools.

When You Need This

  • After disconnecting or replacing the 12 V battery.
  • If a window only moves while you hold the switch and won’t auto-close or auto-open.

Re-initialising Each Window

  1. Close all the doors.
  2. Press and hold the close switch until the window is fully closed, then keep holding for a few seconds, and release.
  3. Press and hold the open switch until the window is fully open, then keep holding for a few seconds, and release.
  4. Repeat for each remaining window.

One-touch should now work again on every initialised window.

If It Still Won’t Work

  • Do both directions — hold at each end for a few seconds.
  • Re-seat the battery connections if you’ve just done battery work.
  • A motor or switch fault can store a code — look it up on autodtcs.com.

Frequently Asked Questions

Why did my Delta windows stop auto-closing?

Disconnecting the battery wipes the window calibration — re-initialise each one.

Do I need a tool?

No — it’s done with the window switches alone.

Do I have to do all the windows?

Yes — each window is calibrated separately.

What does holding at the limit do?

It teaches the module the full travel, restoring one-touch operation.

If you’ve just reconnected the battery, see our Delta battery guide.
