Megane Power Windows Dead After Battery Change

I'm at my wit's end. I've got a 2021 Renault Megane, hybrid engine, and I'm hitting a brick wall. Just changed the battery, and now all the power windows are dead. They won't budge! The error memory keeps throwing up a window regulator initialization error. It's like the car's forgotten how windows work after the battery swap. Anyone else run into this weirdness?

Sounds familiar. I had a similar problem with my Megane (don't remember the exact year). Did you try the window reset procedure?

Window reset procedure? Is that like some secret handshake the car needs to learn? Seriously, where do I find this 'procedure'? And is it, like, a 'guaranteed-to-work-or-your-money-back' kinda thing?

Well, there are multiple reset procedures, and without any diagnostic tool, you probably won't be able to perform one. Then going to a workshop is the best advice I can provide here.

Okay, I took it to the shop after your advice. They had to reinitialize the window regulators with their fancy computer. Cost me 290€, but at least the windows work again. Thanks for pointing me in the right direction!
