2003 cadilac deville driver window off track. motor seems to work but window will not go up.

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.

may be a issue with one of your bcm if you have access to a scanner you can manually control those items to see if it has comunication with the module(s) without that you could try to access each component and test it

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.

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

I, myself own a 1993 Cadillac Sedan Deville. It has over 150K miles on the odometer and has over time had a myriad of parts replaced, mostly by me. One day, for reasons unknown, the window in the driver's side door decided not to work. Like you, all other windows remained fully operable in both directions. While the switches can fail they are, as a rule, quite reliable for long periods of time. When trying, for some time, to get the window to operate, without success, I thought, let me think about this. Upon reflection, I decided that although switch failure is possible the odds of both sets of contacts, raise and lower, failing simultaneously are small.
The next possibility is that the window regulator which is what the manufacturer calls the mechanism, has developed a motor problem. These are DC motors and I don't know whether they have a wound field ar a permanent magnet field. Assuming a wound field it is possible that the last time the window moved under power the motor stopped with a brush either stuck or in contact with a "dead spot" on the commutator. Assuming the latter and with the window fully up I opened the door, pressed the switch to lower the window and while holding the switch in the down position I simultaneously slammed the door. Voila!!! The window went down and became fully operable once more. It has been operating as designed ever since; about 8 months now. Give it a try. Window regulator assemblies are dear and the motor is NOT available as a separate part. Good Luck!!

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.

try putting lube on the window track

from my experience, the window regulators are the problem. Need to replace them.

sound like window switch is bad.

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