Skoda Superb power window issue

Sounds like a faulty regulator motor or the switch itself. I had a similar problem with my old Renault Megane. The car window just stopped, and there was an error code. Have you checked the wiring in the door panel? Sometimes a loose connection can cause these issues. It could also be the window track binding.

Wiring seems ok at first glance, but I'll double check. When you say switch, do you mean the actual button you press to operate the car window?

Yes, I meant the button on the door. In my case, the contacts inside the switch were worn out. Before you go too deep, wiggle the wires going into the switch while trying to operate the window. If it suddenly works, even for a second, that's a strong sign the switch is the problem. But honestly, with an error code stored, it could be the regulator motor itself. If you're not comfortable, a workshop will pinpoint it quickly.

Just wanted to say you were right. A local shop confirmed it was the switch. They installed a new one and the car window works again. The cost was 200€ total. Thanks for the help.
