My window went down, but not up. A guy came along and said it' happened to him in a different make of car. It's a long shot, but it might work. He told me to turn on the ignition, but not turn the engine over. Try the up switch, then use the switch to make the window go down and up 3 times in a row. Try the up switch again. He said that I may have overloaded the circuit at one point and this was a reset sequence. It actually worked..!!
