My passenger window went down yesterday all by itself. I could not power the window closed. It would not go up. I returned home and shut the car off, after a few hours I went back outside and started the car. I pressed the passenger side widow to close the window and it did. I proceed to drive ~2 miles from my house and again, the passenger side widow went down, all by itself. I went home and started looking in the owners manual and on the internet for the cause and solution. Can someone help?
