If the motor runs in either direction, it and the wiring are okay. The problem is almost always a burned contact in a switch. The exception would be if there is a Body Computer involved in running the windows. If there is, first check for a broken wire between the door hinges. The clue is the window will usually work from one switch but not the other one.

When you have a driver's switch and a passenger's switch and neither one runs the window in one direction, there can be a burned contact in either switch. They can be popped apart, then use a thin strip of sandpaper to clean both contacts. You'll usually see the black area from the arcing.
