    I got 2010 Prius, my windows are going crazy on me, see these videos for back and front windows.





    I didn't upload 3rd back passenger window's video, which won't work from master control, only works from the same control in the door. So all together 3 windows not working properly. IDK if it's control switch related or something else?

    That's the sensor that's designed to protect kids and adults from getting their arm stuck in a closing window... Simply clean and inspect the rubber channels the window slides in to find out where its getting jammed up. I've found silicone lubricant spray is a good way to stop this from happening.

    When the window goes all the way up and then dances back, the way your rear-window video shows, that usually means the regulator has forgotten where 'up' is.

    It is programmed to dance back any time it hits something that stops it. It has to learn the one allowed exception ("if you are all the way up, then what stopped you was the top of the door, and that's ok"). See the repair manual (more info) for how to teach it.

    Yes, when the glass is down, I was pushing it up. Master button seems to working fine, it happens even if I use their main controller from the same window.

    I was thinking the same, let me put some lubricant to see if it can help or not.

    I fixed two windows with lubricant, now I can't get the 3rd one fixed I got the main switch and window switch replaced but still nothing, that window will work fine with its windows switch but from master switch it would only go down, not up.

    Any blinking of the switch LED for that window? More info in this post.
