My passenger side window doesn't roll up and it slides down into the door

The window is either out of the track or drive unit broke loose need to open door panel peel plactic and look inside mostlike u will need new windeow regulator

Before the failure, did it make any knocking or griding noises? When you operate the button does the motor make it's normal noise? Did the window become loose and fall down inside the door abruptly? Some vehicles have issues with the "window regulator". This is the cabling device that hoists and lowers the window on the inside rail. Some automakers use plastic bits to keep the window on the rail. If those become loose or break, the window will fall off the tracks. Continued operation of the window will cause the regulator (cables, gear or motor) to fail. If you want to attempt a DIY fix, remove the door cover (a mechanic will usually call this a door card) and see if the window is off the rails. Good luck.
