Powered Rear Window:
* Check the switch: Make sure the switch itself isn't malfunctioning. Try cleaning it with contact cleaner. If the switch is broken, it will need to be replaced.
* Check the fuses: A blown fuse can prevent the window from working. Consult your owner's manual to locate the correct fuse for the rear window.
* Check the wiring: There could be a break or short in the wiring harness between the switch and the window motor. This often requires a mechanic to trace the wiring.
* Check the motor: If the motor is faulty, it will need to be replaced. This usually requires removing the interior panel to access it.
* Check the regulator: The window regulator is the mechanism that moves the window. A broken regulator will prevent the window from going up or down. This is also usually a fairly involved repair.
Manual Rear Window:
* Check the latch: Make sure the latch is properly engaged. There's usually a handle or lever that needs to be pushed or pulled to secure the window in the up position. If it's not engaging properly, you might need to lubricate the mechanism or replace a broken part.
* Check the window track: If the window is binding or sticking in the track, it might not stay up. Clean the track and lubricate it with silicone spray. Bent or damaged tracks may need to be replaced.

* Seek professional help: If you're not comfortable working on your car's electrical system or mechanics, it's best to take it to a qualified mechanic.
