Passenger side window will not work from driver's side

Maybe the main switch is bad.

This happened to me as well. I had the car parked for about 6 months since I was out of the country and no one in the family bothered to start the car while I was gone. When I came back, the passenger side window and the rear passenger window did not work from the drivers side. I was not very happy with it, but I didn't have the time nor the inclination to try to fix it. And after driving it for a few weeks and I had a habit of lowering the other windows just a tad, I would keep hitting the button and within a week or two, they all started working again. I am not kidding, I know it sounds strange, but it really happened. Now they all work fine :)
