Depends on what's wrong with it...
You don't.
To fix a sliding down window, first, check if the window tracks are dirty or obstructed; clean them thoroughly. Next, inspect the window's balance mechanism for any damage or misalignment and adjust or replace it if necessary. Additionally, ensure that the window is properly lubricated with silicone spray to facilitate smooth movement. If the window still slides down, consider installing window locks or stoppers to keep it in place.
Probably need to replace the window regulator.
window make a noise, but won't roll down
The u-braket that stratles the window has probably come off of one side. If you window motor and regulator still work, then the bracket has broken loose from the window. The only way to fix this is buying a new window. The u-bracket comes glued onto the window, there is no other way to fix it. I had both brackets come loose on my 2001, the brackets bolt to the window regulator. Hope this helps.
go to the scrap yard and get a new one.
Hold down the child lock when you press the button to raise the window.
You can try replacing the master control switch on the driver's door. If that doesn't fix it you will need a new window motor.
