2003 deville window off track how do i fix it?

some car door windows have a plastic belt that might have broken, some have gears that might wore down or it may be off track.

You cannot simply get it on "track " its a scissor style window regulator with spools and cables. Done many if these things . They always go bad. Now in the remote chance that it has came off track quote on quote then you have to take the door panel off and make sure that the window is still in the guides .

needs regulator or bolts out to window glass

Window regulator is bad in the drivers door . Do you know what a regulator is ? The Trainer 24 Power Window Troubleshooting Do you know anything about automotive electrical testing ? How to read an use a wiring diagram ? Do you know there are two side to a electrical circuit ? B+ voltage an a ground side . Plus there is electronic control modules and class 2 serial data network involved . When you push the switch for a window othen then drivers window on the drivers door . a class 2 message is sent to the other doors modules . The correct module will then open it's window .

It's not "off Track"

The window regulator broke. Just buy the regulator and not the whole power window assembly. It is a pain to do, but can be done by yourself.

The cable is broken. And unfortunately the motor track and cable is probably one whole assembly. So you need to replace it all as it is one unit.

Remove the door panel,to access the window regulator.
Most likely the regulator will be broken.
If you attempt to just put things back together,they will, as you say,jump off again. e.g. something is worn or broken,so look for that to be your problem

You will have to take inner door panel off and check what moves or doesn't move when trying to use window. It could be off track, something broke or the cable for the window motor is bad. The only way to tell is to look once the panel is off.

no clips...just screws a whole bunch of em...don't forget to disconnect the wires too!
Good Luck (some screws are "hidden" in the armrest.
Good Luck

The window has slipped of the track.Try moving it up and down, back and forth. Gently. Try it.
