Remove the door panel using a screwdriver or special tools.
Locate the window regulator assembly, usually found behind the door panel.
Pull up the window manually by the regulator arm until it reaches the desired position.
If the regulator arm is not accessible or broken, you may need to use a pry bar or similar tool to pry up the window.
Secure the window in place with a temporary clamp or wedge until the window motor or regulator can be repaired or replaced.
