SM3 Power Window Failure

Strange! I drive an SM3 too. Did the windows stop working right after the battery swap? Sounds like what happened to me last year - the window controls just went dead after I disconnected the battery.

Yes, exactly after the swap. Did you manage to solve this yourself, or did you need to visit a shop? I've checked the fuses, and they seem okay. Anything else you tried?

I tried fiddling with the window switch and looking for some kind of reset button, but no luck. In the end, I had to bite the bullet and take it to a workshop. They said something about re-initializing the window regulators. Is it worth the hassle to solve it yourself or is it better to visit the workshop?

Thanks for the info! Sounds like I'm heading to the shop, too. I wanted to avoid it, but re-initializing probably requires special tools. Shop visit done: 290€ later and the window regulators are happy again!
