If you inspect the switch, make sure you have power and ground leaving the switch. There should be a main power in and a main ground in. Then there should be two wires for each window. They alternate polarity based on the switch up or down position. If it is not reversing polarity on the switch for the bad window, then you may have a bad switch. If it is, pull the door panel off and check for the same thing at the window motor plug. You may have a broken wire in the door jamb. It tend to be the driver door jamb as it is used the most. If you have any further questions, feel free to ask.
