Is the motor getting power? is the regulator working? The rear windows will not go all the way down. It is a child protection thing. They will only roll down half way.
The most common window problems in a 2007 Sebring are the fuse, the relay, the switch, and the motor. Check the fuse and the relay. If they are ok then the door will have to have the panel removed to reach the switch and motor.

The wires for the left front window are red/black for up and green/black for white. For the right front window, the wires for up are red/white and the wires for down are green.
If this is the terminal mounted on the window, clear silicone is best.
Try E-Bay or junk yard
