NBox power window failure after battery replacement
Summary of the thread
After replacing the battery in a 2019 Honda NBox, the power windows stopped functioning, and an error related to window regulator initialization was recorded. This issue may be due to the car losing track of window positions when the power was cut. A suggested solution is to perform a window reset procedure by fully lowering and raising the windows while holding the switch. If this does not resolve the issue, consulting a professional technician is recommended, as they can quickly diagnose and fix the problem.

Thank you for your suggestion. I attempted the reset procedure as you described, but unfortunately, the windows remain inoperable. Is there any specific error code you encountered, or any further troubleshooting steps you recommend?

Yeah, that's exactly what happened to me. The reset trick didn't work either, and I got some obscure error code that I can't recall now, sorry. Honestly, after messing with it for a while, I just took it to a workshop. They seemed to know exactly what was up and fixed it pretty quickly. Sounds like the regulators lost their minds. Probably best to have a pro look at it before you mess something up further.

I appreciate the confirmation and advice. Based on your experience, I will consult a qualified technician. The repair cost amounted to 290€. Thank you.

Oh, that sounds familiar! I have an NBox too, and ran into something very similar after my battery died. Did you try the window reset procedure? Sometimes the car forgets the window positions when the power is cut. Hold the window switch down until it's all the way down, keep holding it for a few seconds, and then do the same going up. Does that do anything?
