If your rear windows aren't working, the problem lies with the power window system itself:
* Check the fuses: Consult your owner's manual to locate the fuse(s) for the power windows.
* Check the switches: The switches themselves could be faulty. Try cleaning them with contact cleaner.
* Check the wiring: Look for broken or disconnected wires in the door harnesses, especially where the wires bend and flex as the door opens and closes. This is a common failure point.
* Check the window motors: The motors themselves might be burnt out or seized. This often requires professional repair or replacement.
* Check the window regulators: The regulator mechanism (the system that moves the window up and down) may be broken or jammed. This is also a common point of failure.
Since there is no manual override, you'll need to troubleshoot the electrical system to get them working again. If you're not comfortable working with car electrical systems, take it to a mechanic.
