If the one-touch (auto up/down) function on your Infiniti Q50 (V37, 2013–2023) 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
- Turn the ignition on and close the doors.
- Press and hold the open switch and open the window fully.
- Press and hold the close switch until the window is fully closed, then keep holding for a couple of seconds, and release.
- Check the one-touch operation, then repeat for each remaining window.
If It Still Won’t Work
- Hold the close switch a moment longer after the window seats.
- 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 Q50 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 Q50 battery guide.
