Reinitialise the Electric Windows

Last updated: June 5, 2026

If the electric windows on your Nissan Micra K13 (2010–2017) have stopped going up with a single touch, and now only move while you hold the switch, the window controller has lost its calibration. It happens after the battery is disconnected or goes flat, after a fuse is pulled, or after a window motor or regulator is replaced. The fix is a quick re-initialisation you can do yourself in under a minute per window, with no tools.

Why One-Touch and Anti-Trap Disappear

Each door module needs to know exactly where the window’s fully-open and fully-closed positions are so it can run the glass automatically and stop it if it meets resistance (the anti-trap safety feature). When power is lost, the module clears those references as a precaution. Until you re-teach them, the window only inches while you hold the switch, and the one-touch will not work.

Before You Start

• Sit in the car with the doors closed.
• Turn the ignition on (engine off is fine; the switches must be live).
• Keep fingers and objects clear of the glass — during the relearn the anti-trap protection is not active.

How to Re-initialise a Micra Window

The Micra teaches both end positions — fully open, then fully closed. Do this one window at a time, starting with the driver’s door:

1. Turn the ignition on and close all the doors.
2. Press and hold the switch down to fully OPEN the driver’s window, then release.
3. Pull and hold the switch up to fully CLOSE the window, and once it is shut keep holding for more than 2 seconds, then release.
4. Check operation — a brief tap up/down should now run the window automatically.
5. Repeat for the passenger window.

Once re-initialised, the one-touch up/down returns and the anti-trap protection is active again.

If the Window Still Won’t Auto-Operate

• You missed a step: the Micra needs both the full-open and the full-close (held 2 seconds) taught — do them in that order.
• Glass binding: a dry or twisted runner stops the module seeing a clean end stop. Clean and lubricate the window channel, then retry.
• Anti-trap keeps dropping the glass: friction (often a stiff seal in cold weather) makes the module think it has hit an obstacle. Warm the car, lubricate the rubbers and relearn again.
• Happened after a battery job: that is expected — the window relearn is one of the steps in our Micra battery disconnect/reconnect guide.
• No window will calibrate: if the motor strains or is silent, the regulator, motor or switch may have failed and a body-control fault may be stored — check the code on autodtcs.com.

Frequently Asked Questions

Do I need a diagnostic tool to reset the Micra windows?

No. The relearn is done entirely with the window switch as described. A scan tool is only needed if a genuine motor, regulator or switch fault is stored.

Why do I have to open the window fully first?

The Micra teaches both end stops — fully open and fully closed — so it needs to see each extreme during the relearn. Open fully first, then close and hold.

Why did more than one window lose one-touch at once?

Because they lost power together — almost always after a flat or disconnected battery or a pulled fuse. Re-initialise each one and they all come back.

Is the anti-trap working while I re-teach the window?

No — that is why you must keep hands and objects clear of the glass during the relearn. Full protection returns once calibration is complete.
