Obviously it depends on whats broken...motor, switch, or very likely in these, the window regulator has a plastic part that snapps. Entire Regulator needs replacing. (The regulator is essentially the frame mechanisim that hold and moves the window glasss). Remove interior door panel to do so. Not terribly difficult, but playing around to get the new one to line up right can be tricky....till you get it.

First you have to figure out if it a ad switch, bad regulator or bad electric motor. After proper diagnosis replace the part at fault.

The electric windows on a 406 might behave weird if you disconnect the battery. But holding down the "window-down" on drivers side for 10 seconds or so should fix it.

If it's a window that drops open or a manual/electric window that wont wind down or up, you need to replace your window regulator - about ยฃ25 second hand to replace.

If electric, take it to a garage or trim shop and have it checked out.

The question is too vague. Is the glass broken, does the window get stuck half way, does the window fall down, is the motion jerky, is it manual or electric?

You can use the users manual to learn how to do this. A mechanic can also help you fix this as well.

You would diagnose the problem to determine what the cause is. Assuming this is a power window, it could be the electric motor, the switch, the wiring, the circuit breaker, the relays, the window track, the window regulator and so on.

If an electric window in a Chevrolet Venture will not go up or down, it is likely that a fuse is blown. Replacing the fuse could fix the issue.

If the window is stuck in the down position on a Chevy Silverado, the door panel will have to come off to access the cable mechanism and fix the window. If the windows are electric, there will also be the wiring assembly for the window to remove.

If it's jammed open, sometimes running the engine releases the hold so you can pull it up!

Check the fuse and if it is good then you will have to do some troubleshooting. Can be a bad switch or bad motor.

There is a control power pack located in the drivers door panel which overtime needs to be removed and then re-soldiered to fix a cold soldier joints on the circuit board. This will fix the drivers window from sometime not opening.
