Assuming you can still hear the window motor running when you attempt to roll up the window, the most likely cause is that that plastic track that the motor pushes and pulls the window with has cracked and broken.

To change the window tracks in a 1989 Jeep Grand Wagoneer, first, remove the door panel by unscrewing any fasteners and gently prying it off. Next, detach the window glass by removing the bolts or clips holding it in place, then carefully lift it out. Remove the old window tracks by unscrewing or unbolting them from the door frame, and install the new tracks in their place. Finally, reassemble the window glass and door panel, ensuring everything is securely fastened.
