Today I noticed that the one-touch up and down functions on the drivers window were not working. All of the others work correctly. A fault scan of the drivers door shows:

I checked the measuring blocks and the switch correctly shows the manual and auto positions for both directions when I actuate the switch one and two notches. I have read that you can adapt the regulator by opening the window fully and then closing it and holding the switch for an additional 3-5 seconds. I tried this and it did not work. There is no obvious adaptation for the drivers door controller. Can you tell me how to adapt the window regulator?

The autoscan is attached. Ignore the bulb out warning, that was fixed. It does look like I need to have the dealer check the air flap positioning motor that they replaced earlier this year.

I think I fixed it. I found this on another forum.

Ignition On
Window all the way down
Window all the way up
Let go of switch
Press window switch up again for 2-3 seconds, let go

The regulator should now be re-adaptied.

It seems to work now. Let's see how it works for the next few days.

My question is why did it happen?

I doubt anyone can give you a definitive answer to this.

I suspect it can lose its adapation if there's too much friction, i.e. the motor has to work too hard.

Thank you for explaining that. I was about to take apart my window switch! That worked much better....and easier!
