If a window on your Porsche 718 Boxster or Cayman (2016–present) — the 982 — 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.
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. (The frameless door glass also drops slightly when you open the door — that relies on the same learned positions.)
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 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, anti-pinch and the door-open auto-drop are now relearned.
- Repeat for the other window.
If It Still Won’t One-Touch
- Hold the switch past each limit — letting go early aborts the learn.
- Do it with the door shut so the glass reaches its true closed position.
- A faulty regulator or switch can block the learn — any stored fault can be looked up on autodtcs.com.
Frequently Asked Questions
Why did my 718’s window stop going up with one touch?
The window module lost its learned limits, usually after a battery disconnection or fuse change.
The glass no longer drops when I open the door — same fix?
Yes — the frameless auto-drop uses the learned positions, so re-initialising the window restores it.
Do I need any tools?
No — it’s done entirely with the window switch.
It still won’t work — now what?
Repeat carefully holding the limits; if it still fails, a regulator or switch fault may be stored — check autodtcs.com.
If the windows dropped out after a battery change, see our 718 battery disconnect/reconnect guide.
