Quest power windows failure

I have a Nissan Quest as well, though an older model. I think I recall reading something about a window reset procedure after a battery change on these. You might need to re-initialize the window regulators. Check if there's a specific sequence of holding the window switch up and down. Did you try that?

Yeah, I tried holding the switches up and down for a few seconds, as I saw mentioned on a few forums. Didn't seem to do anything. Is there something more specific I should be doing, or a specific duration to hold the switch? Maybe there's a trick to getting it into the 'learn' mode?

Okay, if the standard reset isn't working, it might be a deeper issue. Considering the error code and that all windows are affected, it could be a more significant problem with the BCM or the window regulator itself. I am thinking a visit to a workshop might be unavoidable. Good luck.

Thanks for the advice. I think you're right; it's beyond my skillset. Ended up taking it to a shop, and they confirmed it needed a proper reset and some recoding. Cost me 290€, but at least the windows work now!
