2004 chrysler sebring.The driver side rear door electric window

Sounds like a connector is disconnected inside the driver side door. The connector is usually located near the front of the door. Removing the door panel could be a job you do not want to attempt, but the car being a 2004 you may want to try. The wiring for the door windows and locks goes through this door.

Start with the cheapest answer and work your way up.
That would mean checking the switches first. Will it work with the window switch nearest it (rear seat switch)? Will it work from the driver's door master switch? If the answer to both is "no", then it is likely the window motor. You can often replace just the motor or replace the window/regulator as a unit.
I would suggest you seek help for that, if you have no idea how to do and you do not have the service manual for the car. It can be complicated getting the old regulator out and removing the glass.

well you can try "jumping" the correct wire to see if window got up or down... this will tell u if switch is bad... but I would just go but a new master switch... try that before you cause more damage..

NO, IF REGULATOR GOES WINDOWS STOP WORKING ALL TOGETHER. IF WINDOWS ARE SLOW AND UNRELIABLE IT'S PROBABLY THE MOTOR.

Most of the time when an issue such as this occurs, the electric motor that operates the window is just stuck, and will need to be gently tapped with a screwdriver, or the wooden end of a hammer. The first thing to do, would be to unplug the switch, and replug it, sometimes it can simply be a bad connection. Try this with the door switch and the electric motor. If that does not work, then try tapping the motor while you, or someone else is operating the switch that will raise the window.

They are off the tracks and must be re-aligned. not something i think you could do without a shop.

No good news here
You know the issues and the routine
Remove the door panels and side interior panel and replace the worn out window regulators on both.

its in the inside door frame when you open the back car you will see a small black switch that you can push up or down and it is usually labeled

cable that lifts it up could have broke you will need to remove door panel and take it out to have a look.Does it make a noise when you operate the switch
