Hello,

This issue is likely a faulty or misaligned window regulator.
The window regulator is what guides the window up or down after the button is pressed. The window motor operates the regulator.
The symptom you are describing it exactly what happens when the regulator goes bad.

In order to access the regulator, you will have to remove the inside door panel. Which is mounted with a few screws and several plastic fasteners.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
