2006 Prius Rear power window malfunction

Check for obstructions... Then try disconnecting the 12volt battery for a few minutes, which resets everything and the window system will re-learn what's closed and what's open.

If that doesn't work next step is to take off the door panel and see if you can see anything that's out of place inside the door.

 

Does "suddenly rolled all the way down" mean it went down at the normal rate or that it fell into the door?

If the latter there is probably a mechanical failure in the door. When that happens you might be able to lift the glass with your fingers, or a palm on each side, but not move it with the motor.

If it rolled down like you were holding the button I would start by examining that switch in the driver's door panel (assuming that was the one you were pushing, if it was the one on the door itself, look there.) The switch might not be bad, it might just be jammed by some grit. This may sound ridiculous, but try slamming the door where the switch is located a couple of times while pushing on the switch up or down. It might dislodge whatever is sticking it in that position if that is the problem. (Do NOT slam the door like this if the glass fell in rather than rolled down. It could be bad, real bad.)

 

Does the window "not go up" if you try the switch at the rear door as well as the driver's master switch?

you either need a window regulator, window motor, window switch, or some combination of those things.

If you are lucky it might just be the interface where the window glass attaches to the "hand" of the regulator that mechanically guides the window up/down.

I had to re-glue my front driver's side window due to that attachment point failing.

I think I used either gorilla glue or E3000 (AKA: Show Goo). GG is more rigid, SG stays flexible and is very tough and durable.
