If a window on your DS 4 (2021–present) has lost its one-touch up/down — usually after a flat or disconnected battery, or a fuse change — you can re-initialise it yourself in under a minute. No tools.
On the DS 4 the one-touch window feature is a convenience function, not a fault warning — when it disappears, nothing is actually broken. The glass still raises and lowers normally while you hold the switch; what stops working is the single-tap automatic travel and the anti-pinch that reverses the glass if it catches something near the top. It is one of the most common after-effects of a 12 V battery being disconnected or run flat, and it may affect one window or several at once. A short relearn from each door switch restores it.
Why It Happens
Each window’s control module learns its fully-up and fully-down stops. Cut the power and that memory is lost, so one-touch and anti-pinch stop working until you re-teach the limits.
How It Works on This Model
Every door has a window motor with a position counter that keeps track of exactly where the glass sits between its top and bottom limits. The express one-touch travel and the anti-pinch protection both rely on those learned reference points — the module uses them to decide when to cut the motor and to judge normal versus abnormal resistance. When 12 V power is removed, whether by a flat battery, a disconnected terminal or a pulled window fuse, that counter is cleared and the motor drops back to move-while-held until the limits are taught again.
Before You Start
- Sit inside with the door shut so the glass can seat fully at the top of the frame.
- Switch the ignition on so the window circuit is fully powered before you begin.
- Keep the run clear — nothing on the seal or in the channel that could stall the glass mid-learn.
- Do one window at a time from that door’s own switch and confirm each result.
- If the battery was just reconnected, leave the car powered up for a few seconds first.
Re-initialising a Window
Do this with the door closed and the ignition on, one window at a time:
- Pull the switch up and hold it until the window is fully closed; keep holding for 1–2 seconds after it stops.
- Press the switch down and hold until the window is fully open; keep holding briefly after it stops.
- Pull up again to fully close and hold briefly — one-touch and anti-pinch are now relearned.
- Repeat for each affected window.
If It Still Won’t One-Touch
- Hold the switch past each limit — letting go the moment the glass stops aborts the learn; the extra second is what registers the end stop.
- Do it with the door shut so the glass reaches its true closed position rather than stopping a fraction short.
- Repeat the up-down-up cycle two or three times if the first attempt only partly takes.
- Check the glass moves freely — a dry or sticky channel can stall the motor before it reaches the stop and block the learn.
- Check the window fuse if a window is completely dead, not just missing one-touch — that is a power fault, not lost memory.
- A faulty regulator or switch can block the learn — any stored fault can be looked up on autodtcs.com.
What to Expect After
Once a window is initialised, a single tap should run it fully up or down on its own, and the anti-pinch should stop and reverse the glass near the top if it meets an obstruction. The setting is stored permanently and survives normal driving — you should not need to repeat it until the next time the battery is disconnected or the window fuse is pulled.
Frequently Asked Questions
Why did my DS 4’s window stop going up with one touch?
The window module lost its learned up and down limits, almost always after the 12 V battery was disconnected or went flat, or after a window fuse was changed. Without those stored positions it falls back to hold-to-move only. Running the up-down-up relearn on that door restores both the express travel and the anti-pinch.
How do I reset the windows?
With the door shut and the ignition on, hold the switch fully up and keep holding a second after it stops, then fully down and pause again, then fully up once more. That single cycle re-teaches the end stops. Repeat on each door that lost the feature.
Do I need any tools?
No. The whole relearn is done with the window switch itself — no scan tool, no fuses to move and no dashboard menu. It costs nothing and takes under a minute per window.
Do I have to do every window?
Only those that actually lost one-touch, though after a battery disconnect several can drop out together. It is quick to run the cycle on each door, so many owners simply do them all at once to be certain everything is back to normal.
It still won’t work — now what?
Repeat the cycle two or three times, holding past each stop with the door closed. If it still fails, check the window fuse and that the glass moves freely. A regulator or switch fault can also block the learn, in which case it may store a diagnostic code worth checking.
Will this happen every time I disconnect the battery?
Yes — any time 12 V power is fully removed, the learned limits are wiped and one-touch may need re-teaching afterwards. It is expected, not a fault, and the quick relearn is simply part of finishing a battery change on the DS 4.
