Kia Troubleshooting Questions? Ask a Mechanic
Either the master switch is not grounding the window up circuit or the relay inside the fuse box is bad. When you push the switch up do you hear a click inside the fuse box that is inside located on the driver side around where your left knee is? If you do not hear the window relay clicking need to get a volt meter and start checking voltages in and out of the window switch and the pins on the back of the fuse box.
