Ecosport power window failure

I am sorry to hear that you are experiencing some trouble with your Ford Ecosport's power windows. It sounds like the replacement of the vehicle battery has caused some disruption with the window control system, as you suggested. May I inquire, have you attempted to reset the window regulators? This can sometimes be achieved by holding the window switch in the 'up' position for a prolonged duration following the battery replacement.

Yeah, I tried holding the switch up, and down, for like 10 seconds each. Nothing. Any other tricks or do I just need to bite the bullet and take it somewhere?

If the prescribed method of holding the window switch in the 'up' position has proven unsuccessful and the error persists, the issue may be more complex than a simple reset. I must suggest arranging an appointment with a qualified automotive workshop. It would be imprudent to suggest more amateur measures that may cause further damage to the electronic system. Best of luck!

Thanks for the input! Ended up taking it to a shop. They had to re-initialize the regulators with their diagnostics tool. Cost me 290€. Annoying, but at least it's fixed.
