C1 power window failure after battery change

Hey! Sounds familiar. I had a similar issue with my C1 after disconnecting the battery for maintenance. The window regulator went completely bonkers. Did you try holding the window switch up and down for a while? Sometimes that can kickstart the initialization.

Thanks! Yes, I've tried holding the switch up and down for about 10 seconds each time, and longer. Still nothing. Can you give me more detail on how you fixed yours?

Ah, damn, that's a bummer. I tried all those 'magic' fixes too, and nothing worked. Eventually, I had to take it to a workshop. They had some fancy computer to reset the regulators. I'm pretty sure you need to take it to a shop.

Thanks. Based on your experience, I'll take it to a workshop. I had the window regulator reinitialized and the error memory cleared for 290€. Hopefully, that fixes it.
