corolla window automat malfunction

friends, my friend has a corolla 2006 model vehicle, which he just bought. The button that raised and lifted the glass was not working. What is the problem, is it a problem we can handle? or can it be made in industry, but how much is it estimated?

you can do a test and understand if there is a problem with my button. Replace the button of another window that works with the button of the glass not working and take a look. No, if it is not a button, the glass automat is inside the door, that is, it is defective or the electricity is not electric. If you have a volt meter, you can check whether the cables coming to the glass automat have electricity or not. Do not forget to press the button while doing this.
