If the one-touch (auto up/down) windows stop working on your Suzuki SX4 S-Cross Mk2 (AK, 2022–present) — usually after a flat or disconnected battery — the motor has lost its learned limits. Re-teaching it on the S-Cross involves briefly pulling the window fuses, then a normal up/down learn. It takes a couple of minutes.
This is one of the most common “something broke after the battery” complaints on the S-Cross, and it is not a fault. The glass and the switches are fine; the window control unit has simply dropped the two end positions it needs to run the motor on its own. Until you re-teach those limits the window moves only while your finger is on the switch, and auto up/down stays disabled.
How It Works on This Model
Each front window on the S-Cross runs on a motor with a position counter, and the controller memorises exactly where “fully up” and “fully down” sit. Those figures let a single tap drive the glass the whole way and tell the anti-pinch protection when to reverse. Cutting 12 V power — a jump-start, a battery swap, or a deep flat — wipes them, so the controller falls back to hold-to-move until re-initialised. On the S-Cross the relearn is preceded by a short fuse pull that clears the controller before the up/down teach.
Getting Ready
- Park up, chock nothing fancy — just make sure hands and fingers are clear of the glass throughout.
- Locate the ‘P/W T’ and ‘P/W’ fuses; the fuse map on the box lid or in your handbook shows their exact positions.
- Have the ignition off to begin, and be ready to switch it on for the learn stage.
- Work one window at a time, from that door’s own switch, so you don’t confuse the controller.
- If the battery is still weak, charge it first — a sagging voltage can stop the learn taking.
How to Re-initialise the Windows
- Turn the ignition off.
- In the fuse box, remove the ‘P/W T’ and ‘P/W’ fuses.
- Pull and hold the window-close switch and wait 15 seconds, then release.
- Refit the ‘P/W T’ and ‘P/W’ fuses.
- Turn the ignition on.
- Press and hold the open switch until the window is fully open.
- Pull and hold the close switch until the window is fully closed, then hold 2 more seconds and release.
- Check one-touch up and down. Repeat for the passenger window, then switch the ignition off.
If It Won’t Stay Set
- Confirm both fuses were the ones removed and are pushed fully home — a half-seated fuse gives intermittent operation.
- Hold a moment longer at the fully-closed stop so the controller clearly registers the top limit.
- Do the full sequence in one go — if you let go early at any stage, start that window again from step one.
- A window that binds or squeaks in its channel can stall the learn; cleaning the rubber runs and adding a little silicone helps the glass reach a true end stop.
- Still nothing after two clean attempts points beyond a lost memory — a tired switch or a window-module fault may be logging a code.
What Happens Next
Once the limits are stored, a single tap sends the glass all the way up or down again, it stops cleanly at the top, and the anti-pinch reversal returns to normal. The setting is permanent until the next time the battery is disconnected, so you only need to repeat this after future battery work.
Frequently Asked Questions
Why did my S-Cross windows stop going up automatically?
A battery disconnect, a jump-start, or a fully flat battery wiped the up and down limits the controller had learned. With no stored positions it drops to a safe mode where the glass only moves while you hold the switch. The fuse-pull and up/down relearn restore one-touch; nothing is actually broken.
Do I really need to pull fuses?
Yes — on the S-Cross the ‘P/W T’ and ‘P/W’ fuses are removed to clear the controller before the up/down teach. Skip it and the relearn often stays half-done, so the auto function won’t hold. Refit both fuses fully before switching the ignition on for the learn.
Which windows need re-initialising?
Every one-touch window that lost the function — typically the driver’s and front passenger’s. Do each from its own door switch, one at a time. It is quickest to run through them all after a battery job rather than find a missed one later.
Do I need any tools?
No special tools. You only pull the two fuses by hand — a fuse puller or fine pliers helps if they are stiff — then operate the window switches. The whole relearn is done from the driver’s seat in a couple of minutes.
Could this happen again?
Yes, any time 12 V power is interrupted — a future battery replacement, a jump-start, or a battery that goes flat while parked. It is harmless, just a cleared memory. Keep this sequence handy and you can restore one-touch in minutes each time.
What if only one window is affected?
That is normal — sometimes only one motor drops its memory, or you notice one first. Re-initialise just that window from its switch. If it refuses to learn while the others behave, the cause is more likely that door’s switch or motor than a lost setting.
